Description Tom Kijas 2011-11-30 07:29:33 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1.4-030104-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Hi, my plasma crashes every time I boot-in
- Unusual behavior I noticed:
Nepomuk crashes, plasma crashes, KDE asks me for password for IMAP account every time without telling me when email comes then, plasma-widget-networkmanagement doesn't remember passwords.

The crash can be reproduced every time.

-- Backtrace:
Application: Shell plochy Plasma (plasma-desktop), signal: Segmentation fault

Comment 1 Aaron J. Seigo 2011-11-30 09:12:04 UTC

sounds like you have a number of issues with your installation :/

this crash is happening in the Qt JavaScript engine from a script loaded by the comic applet. from a konsole screen can you please run:


tar cjf comicscripts.tar.bz2 `kde4-config --localprefix`/share/apps/plasma/comics

and then upload the comicscripts.tar.bz2 file as an attachment to this report. thanks.

(you can also in the meantime remove reference to the comics plasmoid in plasma-desktop-appletsrc and, assuming the installation is not completely messed up, plasma-desktop should start again)

Comment 2 Blagovest Zlatev 2011-12-01 11:36:01 UTC

This bug looks like bug 283151.

Comment 3 Aaron J. Seigo 2011-12-06 13:37:14 UTC

*** Bug 283151 has been marked as a duplicate of this bug. ***

Comment 4 Martin Flöser 2013-05-28 20:06:33 UTC

Thank you for this crash report and helping to improve our software. Unfortunately we were not able to work on this specific report yet. Nowadays the version this crash was reported against is no longer maintained and this makes it very difficult to work on this report as the source code might have changed and the information in the backtrace is no longer valid.

Also it is quite likely that this problem got fixed in a later version. Crash reports are very often reported multiple times.

If you are able to reproduce this crash with the latest version of KDE Plasma (4.10.3) please reopen this report and adjust the version information in the dropdown above and please also include a new backtrace as generated by the crash reporting tool. Please also make sure that the steps on how to reproduce the crash are precise and correct. Thank you!
