Application: apper (0.8.1)
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.24-default x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I had 7 elements checked for updating and agreed, when another Apper windows came from nowhere...showing the same elements that already being updated...I clicked on Review (cause I could not close the window) and Apper crashed. Why can Apper not see that he is already started ???

The crash can be reproduced every time.

-- Backtrace:
Application: Apper (apper), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
