Can you reproduce the crash after clearing the cache? (click the Clear Cache button in "The previous session crashed." dialog that appears on KDevelop start after a crash)
(In reply to Igor Kushnir from comment #1) > Can you reproduce the crash after clearing the cache? (click the Clear Cache > button in "The previous session crashed." dialog that appears on KDevelop > start after a crash) After clearing cache last time it worked for a bit before starting to crash again - I have cleared the cache once more and so far it is working.
KDevelop sometimes takes a long time to exit, especially after reparsing a big project. Sometimes it even hangs indefinitely. Though in my recent experience eventually KDevelop finishes its work and exits cleanly. Check a system monitor to make sure that a kdevelop process is not running when you shut the system down. See Bug 463497.
