Description Gregor Petrin 2009-06-14 18:19:15 UTC
Application that crashed: k3b
Version of the application: 1.66.0
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 139"
Qt Version: 4.5.1
Operating System: Linux 2.6.27.23-0.1-pae i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
I was able to reproduce the crash several times:

1) Open a directory in the K3B filesystem browser
2) Delete this directory from another program (Krusader in my case)

This causes K3B to immediately crash.

I can confirm this crash with a more or less recent svn checkout with KDE-4.2.4 (+personal patch to fix bug 195986 for me).

Simple (more verbose) backtrace:

I can also confirm this crash.
Comment 4 eightmillion 2009-08-17 23:12:22 UTC
I suppose I should also add that I'm using K3b 1.66.0 alpha 2 on KDE 4.3.00
Comment 5 Michał Małek 2009-09-14 20:06:41 UTC
Could you check this bug on current trunk? I cannot reproduce this, maybe it's already fixed. Thanks

In an attempt to clean up old bugs that are not valid for K3b 2.0 (=KDE SC 4.x port) anymore, this is now being marked as UNMAINTAINED.
If this bug is still valid for 2.0, please reopen it.
