I have a similar problem, I get the error "Internal Error. Application "Contacts" closed". I use Titans Kernel V28 and everything works fine @ 900 MHz + ULV profile. The issue appears ONLY with the contact list, no other application shows it even after hours of heavy usage.

There is a way to fix the issue temporary:

1. Disable the MSN Butterfly plugin (Works most of the time)

Is that bug in the Titan kernel?
