Description Marc Schiffbauer 2009-07-08 00:54:26 UTC

Version:           4.2.95 (using Devel)
OS:                Linux
Installed from:    Compiled sources

Whenever kmail within kontact tries to fetch mail (dimap) and the connection fails, a dialog pops up telling the user about the connection failure.

After clicking "ok" then, kontact crashes

This is reproducable here.

As you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks

Comment 2 Marc Schiffbauer 2009-07-13 14:39:04 UTC

Waiting for the next crash it seems it is not so reproducable than I thought it is...

As soon as it happens again I will post the backtrace.
