I have a project folder, /home/myuser/git/project, and whenever I try to perform an operation there from the command line, the process gets killed.e.g.$ rm -Rf .toxKilled$ python setup.py installKilledGoogling shows that this is caused by the kernel terminating the process. When I look in /var/log/kern.log, I see:Oct  4 19:44:51 localhost kernel: [1362505.472155] BUG: unable to handle kernel NULL pointer dereference at           (null)Oct  4 19:44:51 localhost kernel: [1362505.473347] IP: [<ffffffff81218356>] lookup_fast+0x2a6/0x330Oct  4 19:44:51 localhost kernel: [1362505.474559] PGD 1c4b90067 PUD 3ace3f067 PMD 0 Oct  4 19:44:51 localhost kernel: [1362505.475741] Oops: 0000 [#31] SMP Oct  4 19:44:51 localhost kernel: [1362505.476949] Modules linked in: dm_crypt algif_skcipher af_alg uas usb_storage cdc_acm cmac rfcomm xt_CHECKSUM iptable_mangle ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_nat_ipv4 nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp bridge stp llc bnep ebtable_filter ebtables ip6table_filter ip6_tables drbg ansi_cprng ctr iptable_filter ccm ip_tables x_tables pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) binfmt_misc nls_iso8859_1 uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core v4l2_common ath3k btusb btrtl videodev btbcm media btintel snd_hda_codec_hdmi snd_hda_codec_realtek joydev intel_rapl snd_hda_codec_generic bluetooth snd_hda_intel snd_hda_codec x86_pkg_temp_thermal snd_hda_core intel_powerclamp arc4 snd_hwdep coretemp kvm_intel snd_pcm ath9k ath9k_common ath9k_hw snd_seq_midi snd_seq_midi_event kvm irqbypass ath mac80211 snd_rawmidi crct10dif_pclmul crc32_pclmul cfg80211 snd_seq aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper snd_seq_device input_leds cryptd mei_me snd_timer serio_raw mei snd soundcore shpchp lpc_ich acpi_pad acpi_als kfifo_buf mac_hid industrialio parport_pc ppdev lp sunrpc parport autofs4 hid_apple hid_generic usbhid hid i915 i2c_algo_bit drm_kms_helper syscopyarea sysfillrect sysimgblt r8169 fb_sys_fops ahci psmouse libahci drm mii fjes videoOct  4 19:44:51 localhost kernel: [1362505.486653] CPU: 3 PID: 13542 Comm: rm Tainted: G      D W  OE   4.4.0-36-generic #55-UbuntuOct  4 19:44:51 localhost kernel: [1362505.488550] Hardware name: Intel Corporation SharkBay Platform/WhiteTip Mountain1 Fab2, BIOS 5.6.5 06/18/2015Oct  4 19:44:51 localhost kernel: [1362505.490102] task: ffff8803baa5e040 ti: ffff8802fcf4c000 task.ti: ffff8802fcf4c000Oct  4 19:44:51 localhost kernel: [1362505.491628] RIP: 0010:[<ffffffff81218356>]  [<ffffffff81218356>] lookup_fast+0x2a6/0x330Oct  4 19:44:51 localhost kernel: [1362505.493144] RSP: 0018:ffff8802fcf4fc50  EFLAGS: 00010202Oct  4 19:44:51 localhost kernel: [1362505.494644] RAX: 0000000000000000 RBX: ffff8802fcf4fd30 RCX: ffff8802fcf4fcacOct  4 19:44:51 localhost kernel: [1362505.496091] RDX: 0000000000000000 RSI: 0000000000000040 RDI: ffff88000864d000Oct  4 19:44:51 localhost kernel: [1362505.497848] RBP: ffff8802fcf4fc98 R08: 0000000000000001 R09: ffff88000866f01cOct  4 19:44:51 localhost kernel: [1362505.500084] R10: 000000006d94c509 R11: ffff88000864d040 R12: ffff88000864d000Oct  4 19:44:51 localhost kernel: [1362505.501975] R13: ffff8802fcf4fcb8 R14: ffff8802fcf4fcb0 R15: ffff880431597820Oct  4 19:44:51 localhost kernel: [1362505.503555] FS:  00007f5d41391700(0000) GS:ffff88044ed80000(0000) knlGS:0000000000000000Oct  4 19:44:51 localhost kernel: [1362505.505126] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033Oct  4 19:44:51 localhost kernel: [1362505.506700] CR2: 0000000000000000 CR3: 000000043a6f2000 CR4: 00000000003406e0Oct  4 19:44:51 localhost kernel: [1362505.508251] Stack:Oct  4 19:44:51 localhost kernel: [1362505.510425]  ffff8802fcf4fcac ffff880200000000 0000000281217948 000000005cdfe718Oct  4 19:44:51 localhost kernel: [1362505.513064]  ffff8802fcf4fd30 0000000000000000 0000000000000000 ffff8802fcf4fe70Oct  4 19:44:51 localhost kernel: [1362505.515607]  ffff8802fcf4fec0 ffff8802fcf4fcf8 ffffffff81219da9 00000002fcf4fd50Oct  4 19:44:51 localhost kernel: [1362505.517399] Call Trace:Oct  4 19:44:51 localhost kernel: [1362505.518663]  [<ffffffff81219da9>] walk_component+0x49/0x300Oct  4 19:44:51 localhost kernel: [1362505.519860]  [<ffffffff81219a85>] ?

Why is rm crashing or being killed by the kernel, only when accessing this one directory?I'm running Ubuntu 16.04.
