Description Robin 2014-10-17 10:58:32 UTC 
Application: plasmashell ()

Qt Version: 5.3.0
Operating System: Linux 3.16.0-22-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
- What I was doing when the application crashed:
I think I was clicking on the base folder in the folder manager programme. During this, fstab was opened in sudo-mode via kate. I'm sorry I can't provide very detailed information, but I'm not an expert. Please let me know if there's anything else I can do to help. :)
Kubuntu 14.10 (Plasma 5 beta 2) is mostly up to date, at least I installed updates yesterday

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault

An https://bugs.kde.org/ berichten

Reproducible: Sometimes

Steps to Reproduce:
1. Using Kubuntu 14.10 Plasma 5 preview, open the folder manager/file manager and click on folders, browse, and sometimes the error message plops up.
2. Not sure if relevant, but during the crash, fstab was opened via kate in sudo mode (opened with terminal)
3.

Actual Results:  
Sometimes, it just crashes, leaving my system without the control panel on the bottom, giving me the crash error message and making me reboot. The desktop is black, too, but the already opened windows remain.

Expected Results:  
It shouldn't have crashed, I guess

My system:AMD Radeon HD 7950, Intel i5-2400, 2x 4GB DDR3@1333Mhz, Asrock P67-Pro motherboard.
I also need to add, I'm not sure which component to assign this bug to. Sorry! (And I hope this hasn't been reported already, I was looking through some bugs but I'm not sure if this exact thing is known already)
Comment 1 David Edmundson 2015-01-04 16:45:17 UTC 
Thanks, the two crashes are in exactly the same place

Kickoff::ApplicationModelPrivate::fillNode so it seems to be the same cause, even if they are happening at different times.
