valgrind --track-origins=yes --num-callers=25 kdevelop

and attacht the report.

Comment 2 Musikolo 2011-02-28 22:17:07 UTC 
Created attachment 57581 [details]
Output of "valgrind --track-origins=yes --num-callers=25 kdevelop"

Steps to reproduce:

1.- From the "Code" tab, click on the "Review" tab with no files open (empty).
2.- Select a modified file: Git --> Compare to Base...
3.- Click on the "Finish Review" button and it should go to the "Code" tab
4.- Click again on the "Review" tab and it should be empty (no files open)
5.- Click on the "Show" button --> CRASH!!

I hope it helps!
