Description Dennis Schridde 2011-02-03 21:45:18 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 wanted to view the details of a key in my list (via r-click). kgpg responded that gpg had a problem (unsupported/unrecognized/unknown option --debug-level). When I clicked ok, kgpg crashed.

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

Comment 1 Rolf Eike Beer 2011-02-03 23:00:24 UTC
Which gpg version are you using (gpg --version will tell you). I thought I had this debug-level stuff fixed already.
Comment 2 Dennis Schridde 2011-02-04 09:03:08 UTC
1.4.10 (gpg) and 2.0.14 (gpg2)
Comment 3 Rolf Eike Beer 2011-02-06 21:51:52 UTC
For the moments things might get better if you go into the KGpg configuration and configure it to use gpg2.
