Description Dennis Schridde 2011-02-03 21:37:37 UTC

Application: kgpg (2.4.92)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-26-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was in the config widget when I was asked to start the assistant to figure out the gpg config. I selected to start the assistant, but did not notice the window opening in the background. Hence I clicked again, starting another instance. Then I finished the first assistant, saw the 2nd, finished it too, kgpg crashed.

-- Backtrace:
Application: KGpg (kgpg), signal: Segmentation fault

Comment 2 Rolf Eike Beer 2011-02-22 19:53:05 UTC

Is there a chance that you could test the current trunk to see if that now works for you?

Doubtful. I am in no hurry and will just check the next release.

Comment 4 Rolf Eike Beer 2011-10-23 17:31:19 UTC

Can you please retest with the current version?
