Description srudloff 2007-05-05 09:47:07 UTC

Version:            (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages

When I write in a channel with blowfish encryption and a very long key konversation don't encrypt the channel right and when I write something it crashes.
Here are the backtrace and the console output:

liquid@ubuntu:~$ konversation

Comment 1 Eike Hein 2008-05-01 13:06:48 UTC

The blowfish code in Konversation has just seen revision and a number of bugfixes, related to key management and encoding, in the SVN version. If possible, please re-test with the SVN version. Instructions for how to retrieve the SVN version can be found here: http://konversation.kde.org/wiki/SVN

Note: In order for backtraces to be useful, debug symbols need to be installed. Many distributions provide these in separate packages, e.g. a 'konversation-dbg' package. For self-compiled versions or source-based distributions, the advice given in http://www.gentoo.org/proj/en/qa/backtraces.xml broadly applies.

Comment 2 Eike Hein 2009-05-13 01:16:31 UTC

Does this still happen for you with Konversation 1.1 or the pre-release KDE 4 port?

Comment 3 Eike Hein 2009-10-11 20:39:40 UTC

The Blowfish code has been nearly entirely rewritten for the KDE 4 version and development of the KDE 3 codebase has ceased.
