solid bug (yikes!)
Comment 2 Pradeep K. Shima 2012-04-02 09:12:38 UTC 
OK more info ...

Reporducing this crash is very very easy ...

1. Launch kdevelop
2. On another konsole window, run "umount -a"
3. Enjoy the crash.

I use automount, so this crash happens every few minutes, so I am not able to use Kdevelop anymore.
