I'm attempting my first IOS build from Unity 3d. 

Here's some of the output from the dump after Xcode dies. I've done a fetch/retrieve of a new developer certificate, and it seems valid in the keychain. I've also removed all old provisioning profiles from the IOS device (iphone 4S) attached. I tried removing Xcode and reinstalling it to no avail. The iphone actually does actually show up under Window->Devices in xcode. When I right click on the iphone in the device list and look at provisioning profiles I get the following:
iostpp:com.jaqen2525.hb1 Ad Hoc
iostpp:com.jaqen2525.hb1 Dev
and two others that I'm not using: so the new provisioning profiles are there, and the development certificate under the keychain looks fine, though there is one that is not quite working:
Lee Bererton's CA: This root certificate is not trusted. So I trusted it in my keychain access by right clicking and getting Info, then clicking on choosing to trust it.

Also of note, any attempt under Xcode->Preferences->Account, then opening up the provisioning profiles consistently crashes Xcode
Xcode still crashing, any thoughts?
