Description Gerard Wypych 2015-08-19 17:55:26 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

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

It was right-click on the screen, then i choose the last option from the list, Wallpaper and Layout (it is called "Układ" in polish). I changed settings from deafault "Desktop" to "Catalogue"/"Folder" (i don't know how it is named in english).  Then i moved "Home" folder to another place on the screen. Next was information about crash.

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

Comment 13 Marco Martin 2015-10-14 14:47:06 UTC 
the garbage collector crashes were known to be caused by the multiple qml engines per applet.
please reoplen if this BT stll happens with Plasma 5.4 or more recent
Comment 14 Nico R. 2015-10-25 21:39:25 UTC 
Came here via https://bugs.kde.org/show_bug.cgi?id=352904 because only after upgrading from Kubuntu 15.04 to 15.10, the behavior described there occurred to me.

Apparently, no debug symbols for the libraries in question were found, so I only got this small backtrace for the crash which occurs every time I'm adding a System Tray widget to a panel; plus, plasmashell appears to hang for 1-2 minutes after restarting, eventually displaying the panel and widget.

Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-16-generic x86_64
Distribution: Ubuntu 15.10

Application: Plasma (plasmashell), signal: Segmentation fault

Comment 15 Nico R. 2015-10-30 14:42:45 UTC 
Update: Had an update of Ubuntu package plasma-nm, after which the problems with my systray widget disappeared. So that wasn't obviously connected to the issue described in this report.
