Description A. Sala 2013-03-07 13:32:04 UTC

Application: kleopatra (2.1.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I imported all certificates in /usr/share/ca-certificates/mozilla.
Nothing was shown... I rebooted and they were shown.
Now, the root certificates are untrusted. Selecting one and with right-clicking trying to move it to the trusted root certificates crashes Kleopatra.
I tried it with three different crt's and the behaviour is repeated.

The crash can be reproduced every time.

-- Backtrace:
Application: Kleopatra (kleopatra), signal: Segmentation fault

New crash information added by DrKonqi

kleopatra (2.1.1) on KDE Platform 4.9.5 using Qt 4.8.3

- What I was doing when the application crashed:

I was marking an untrusted GPG key as trusted (this is not just about root certificates).

Comment 2 Emanuel Schütze 2013-05-10 07:52:57 UTC

Can't reproduce it with Kleopatra (KDE 4.10.3) of Gpg4win on Windows.

Comment 3 A. Sala 2013-05-13 11:38:39 UTC

In my case, it seems that 4.10.3 (in Kubuntu 13.04) does not segfault, too...
 however, it does not trust the certificate I tried to trust, so this has been not solved correctly as the expected action (import it on the trusted certificate list) does not yet occur.

Comment 4 Emanuel Schütze 2013-06-24 15:28:31 UTC

@A. Sala: 
If Kleoaptra 2.1.1 does not segfault no longer you should create a new bug report with your current "it does not trust the certificate I tried to trust". Please report a step by step instruction to reproduce it with 2.1.1.
Thanks.
