Description Maarten Bezemer 2012-05-16 08:52:34 UTC

Application: muon (1.3.1)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

* I added ppa:ubuntu-wine/ppa as new software source.
* Deselected the source line for wine
* Closed the dialog

And Muon crashed, just after its window (the list of available packages) became empty, as it does when updating the packages.

I restarted Muon, that seemed to be worken, but when I clicked 'Check for Updates' it crashed again.

After submitting this report, I'll check whether the backtrace is different and add that one as well to this report.

PS DrKonqi could not send the bug report: "There is no component named 'general' in the 'muon' product." So, I have send it manually... But I suppose some DrKonqi/Muon configuration needs to be fixed as well...?

-- Backtrace:
Application: Muon Package Manager (muon), signal: Segmentation fault

Comment 2 Maarten Bezemer 2012-05-16 08:56:52 UTC

And now muon-updater also crashes...
I'll post the /etc/apt/sources.list.d/ubuntu-wine-ppa-precise.list contents as well, as this is the change I made (see post #1):
deb http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu precise main
# deb-src http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu precise main

Comment 3 Maarten Bezemer 2012-05-16 09:00:42 UTC

In order to have Muon working again, I checked the sources line in Configure Software Sources again, ie removed the # in the /etc/apt/sources.list.d/ubuntu-wine-ppa-precise.list file.

And now the crash is gone...

In also have some more details when the crash happens: it happens when the progress bar of 'Rebuilding Search Index' (shown in the bottom right corner of the Muon main window) is almost complete.
