plasma netbook shell crashes on kubuntu 12.04 and 12.10

[Jonathan Aquilina]

Hey everyone I am encountering this annoying seg fault crash on 12.04 and 12.10 with kde 4.8.2 and 4.8.3.

The issue occurs when i have my usb external hard disk connected and im using multiple tabs in dolphin to sort my files on this particular drive. first time i get the bug reporter and am able to get a back trace, and the desktop restarts. When it happens the second time i dont even get the bug report just have any applications that are open on my system left and am unable to open any other applications.

the netbook im running it on is an asus eee pc 1001px running a 60gb OCZ Agility 3 SSD.

the back trace is below

Application: Plasma Netbook Shell (plasma-netbook), signal: Segmentation fault

[Jonathan Aquilina (eagles051387)]

It seems that the menu bar for me has taken the focus on my chromium tabs.

[Aurélien Gâteau (agateau)]

This backtrace is very different from the previous one. It looks like an exception, which is very strange because neither plasma-widget-menubar not dbusmenu-qt use exceptions. Can you restart plasma-netbook from a terminal to find if it prints out any error message right before crashing?

[Jonathan Aquilina (eagles051387)]

Once packaged I am willing to test this package :)

[Philip Muškovac (yofel)]

Fixed in quantal upload of 0.1.18-0ubuntu1

[Jonathan Aquilina (eagles051387)]

hey guys sadly 0.1.18 doesnt fix the issue i have the same issue as in post number 6 but i must say 18 has gotten rid of the crash though.

[Jonathan Aquilina (eagles051387)]

I dont know if this is related to the above issue, how can i determine the app which is sig aborting?

hey guys I got bold this morning and I wanted to try remove kde all together and reinstall it via the meta package. I purged kubuntu-desktop then i did it again doing kubuntu-* since it didnt get all of the desktop. I rebooted and for some reason i have kde still installed but the normal desktop version and not the netbook version. all menus bar at the bottom works flawlessly. it seems like those crashes are netbook specific.

[Jonathan Aquilina (eagles051387)]

ok just restarted and reinstalled kubuntu-desktop meta package after purging and set it to desktop and i have the upper menu bar as well as the one on the bottom. if i set it to netbook only it does not show up correctly. which now just crashed and sadly i wasnt able to get a back trace :(

oddly now setting netbook in system settings i have 2 menu bars one at the top one at the bottom :(

Status changed to 'Confirmed' because the bug affects multiple users.

[Dennis Schridde (devurandom)]

Version 0.1.18 appears to fix KDE bug #283388 [1] here. Please update the Ubuntu 12.04 package to that version.

[Adam Porter (alphapapa)]

Yes, after installing the 0.1.18 package, the crashes seem to be fixed. Please backport this to Precise!

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
