loading c++ project crash on 64bit machines

[Alexander Dymo]

After spending some time to reproduce the problem at irc we've finally 
found a way:
1) Have a 64 bit machine with 64bit OS (SuSE 10.1 in my case)
2) create a simple kde project and close kdevelop without closing
  the project so it would get loaded next time
3) go to konsole and run kdevelop, but don't let its window to be shown,
 do something in konsole so that you see only kdevelop splash at maximum
4) have a crash with included backtrace or have all your memory eaten

I've looked at it but didn't understand why it happens so far. David, could
you please help?
