After this it crashes everytime I try to load a faulty session. I can start KDevelop in pick-session mode and then choose to create a new one. It works. However, if I try to switch to the faulty one, it crashes again. The crash can be reproduced every time. -- Backtrace: Application: KDevelop (kdevelop), signal: Segmentation fault Using host libthread_db library "/lib/i386-linux-gnu/i686/cmov/libthread_db.so.1".

I just remembered that I've very recently updated Qt from 4.7.4 to 4.8. So maybe this is the cause of the crash
please run it through valgrind if it's reproducible. line 267 for me reads: 266: QMultiMap<QString, Sublime::View*>::iterator it = recycle.find( specifier ); 267: if( it != recycle.end() ) I think this should be perfeclty fine. make sure your kdevplatform checkout is up2date as well.
I've recompiled kdevplatform and kdevelop (using new qt, so it has to recreate all moc files). Kdevelop at start asked to clean the cache since it crashed two times in a row. And it works. So it appears that I cannot reproduce it anymore and for me it's solved.
ok thanks, there were some fixes in this area recently, lets hope it's fixed then
