Description Ryan 2018-01-04 04:36:06 UTC 
Application: plasmashell (5.11.5)

Qt Version: 5.9.3
Frameworks Version: 5.41.0
Operating System: Linux 4.10.0-42-generic x86_64
Distribution: KDE neon User Edition 5.11

-- Information about the crash:
- What I was doing when the application crashed:
Added a new city to the weather widget. When first install widget it showed weather. After reboot there was just a question mark. Opened it and added anothe nearby city. Seem to update then desktop crashed. System monitor widget crashed and went into top panel. Tried to move it and desktop crashed again. 
- Unusual behavior I noticed: System monitor widget moved to secondary task bar. When tried to move it crashed and disappeared.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

i can reproduce it sometimes by dragging a systemmonitor plasmoid (like cpu) between desktop and panel https://phabricator.kde.org/D10250 may adress this issue

disconnect render() on window change

Summary:
when the window changes, the node will be deleted, and render()
will access an invalid pointer.
disconnect the render slot when the window change, as it
can't do anything useful until the next updatepaintnode.
Make the managedtexturenode actually do the management, as
textures were never deleted
Related: bug 374280, bug 365052, bug 343576

Test Plan:
The bug is easily reproducible without the patch, wasn't
able to reproduce it anymore with it
