Crash Bug

Postby daybreak on Wed Aug 31, 2011 10:54 pm


I have a crash for the latest Beta(2111) and before. Simply open it with the editor. It is not really a zip file, just named so to get attached. Below is a little debugging info about the crash. Done on Mac OS X 10.6.6.


Code: Select all

0x00007fff8841e7f0 in CFStringCreateCopy ()
