The crash can be reproduced every time.

New crash information added by DrKonqi

kstars (2.0.0) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4

- What I was doing when the application crashed:

Trying to launch Kstars several times. It might be related to this crash because I do seem to recall updating data files to include more stars before this started happening. I cannot run kstars at all. It starts up but crashes immediately. I will try to delete the Kstars data directory and see if this helps.

Comment 2 David Charles Pyle 2011-10-03 06:20:33 UTC

I just deleted the kstars data files out of the kstars directory (located in /home/<username>/.kde/apps/) and kstars now launches and runs without errors. Something involving adding additional stars dat files causes the crashing on startup. I do not know what it is at the moment but clearing the kstars directory stopped the repeated crashing. So far the program is working again.

I have no attachments to add at the present but will add more data as I find the time.
