How to fix "unfortunately , the process com.android.systemui has stopped" error? Recently, I flash cm-11-20140504-SNAPSHOT-M6-maguro.zip to my Galaxy Nexus GSM. And I flash PA gapps. And after that, I used Titanium backup to restore  all my applications. However, I met this unfortunately , the process com.android.systemui has stopped error sometimes. How can I fix it without doing a factory reset.

PS. If I enter the recovery and clear cache, it will be OK. However it is too annoying to do it each time. Is there other way to fix it. Or is it a bug in this version?

I have been experiencing this as well on the same build/phone.  A user on this thread claims that M5 may be much less error prone.  

I haven't reverted to M5 yet myself.  When this error loop happens to me, I hold down the power button and try to select "reboot" between the times when I hit ok in the "Unfortunately... " box.
