Description Luke Plant 2009-09-16 14:01:45 UTC
Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Steps to reproduce:

1. Add 'System monitor' plasmoid to panel
2. Click on it, and click on one of the icons to add a monitor (e.g. the internet icon)
3. Click on the icon again (to remove the monitor).

Result: plasma crashes.  Every time for me.

KDE version: KDE 4.3.1, packages from Ubuntu Jaunty kubuntu backports

Comment 1 Dario Andres 2009-09-16 14:23:44 UTC
The backtrace is likely to be bug 205660. Can you install the "kdebase-workspace-dbg" package and paste here a new backtrace?, so we can compare them.
Thanks

Thanks

bug 205660 is marked RESOLVED FIXED, yet the only comment on it states that the backtrace seems to be wrong - there is no explanation of how the bug was actually fixed, if it has been.

That was in KDE 4.3.0, and this crash occurred in KDE 4.3.1, so whatever the state of the backtrace, the bug seems to be still alive.  Has there actually been a commit that has fixed this?
Comment 6 Dario Andres 2009-09-23 18:05:49 UTC
Ok, let's get a complete backtrace before deciding it.(situations matched, and it seems to be an Ubuntu error)
Please install the "kdebase-workspace-dbg" package, repeat the crash situation and paste here a new backtrace. Thanks
Comment 7 Dario Andres 2009-09-23 18:10:38 UTC
Sorry, I just misread something.. err

I marked both reports as duplicates as the backtraces match, the line numbers didn't changed from 4.3.0 to 4.3.1

It may not be fixed, but it seems to be an Ubuntu error, as the lines do not match with the official KDE code:
http://websvn.kde.org/tags/KDE/4.3.1/kdebase/workspace/plasma/applets/system-monitor/system-monitor.cpp?view=annotate

Regards
