-- Information about the crash:
Greetings..

I have cleaned all of the settings I could find, the .kdev4 files, KDevelop starts up properly, but when I try to load a source file (any of many), it crashes. I didn't load any projects or anything. I was getting the same crash (I think) before I had cleaned out the settings, except it was *right* when it started and tried to automatically load the files. It seems like it happened quite recently, as it was stable a few days ago. Looks like yesterday's trunk *may* have broken it? Don't quote me on it though.

The crash can be reproduced every time.
