Description becker1991 2011-11-20 21:41:41 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
The plasma framework crashes frequently when I shut down my PC. This is not only annoying, it stops the shutdown process and leaves my PC unable to shutdown. As a result, I have to do a lot of cold resets.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation fault

Comment 1 Lamarque V. Souza 2011-11-21 13:01:24 UTC

This looks like a duplicate of #272495 or #281074. Which plasma NM version do you use? You see the version number in the kcm module (Manage Connections -> Other).

 plasma-widget-networkmanagement is 0.9~svngit.nm09.20110610.0c83d8-0ubuntu5

Comment 3 Lamarque V. Souza 2011-11-21 14:29:46 UTC

By what I could see in the source code downloaded from https://launchpad.net/ubuntu/+source/networkmanagement/0.9~svngit.nm09.20110610.0c83d8-0ubuntu5 that package misses the fix for #281074. Marking this bug as a duplicate of #281074.

Please contact Ubuntu to update their networkmanagement package to Plasma NM 0.8.95 (http://lamarque-lvs.blogspot.com/2011/11/plasma-nm-0895.html). The fix for #281074 was commit more than two and half months ago and is included in 0.8.95.
