Description Amichai Rothman 2016-06-20 06:31:21 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-24-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- Unusual behavior I noticed:
Whenever the monitors should go into energy saving mode (after not using the pc for the specified amount of time), the screens do go blank for a few seconds, but then turn right back on. This is accompanied by a plasma crash dialog. If I leave the pc for several hours, I come back to a whole pile of such crash dialogs on top of each other.

On Kubuntu 16.04,  kernel 4.4.0-24-generic, Intel Graphics 4600 (Haswell), plasma-desktop 4:5.5.5-0ubuntu1.

The crash can be reproduced every time.

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

Would you be able to install debug symbols for plasma-framework and reproduce.
Comment 2 David Edmundson 2016-06-30 20:40:41 UTC 
Also, can you tell me what theme you're using.
Comment 3 Amichai Rothman 2016-07-01 04:37:59 UTC 
The theme is Breeze.

I think I did select to load debug symbols from the crash dialog - how should I install whatever is missing?

there should be a package called plasma-framework-debug or something like that (varies between distributions)
Comment 5 Amichai Rothman 2016-10-28 08:13:44 UTC 
This issue stopped happening a while back, after I deleted one of the config files (I don't remember exactly which, probably one of the plasma*rc).

It's unfortunate that plasma crashes due to a config file, which itself was modified only by the software, never by me manually - so there may be additionally another bug of how the config file got to that state, if it is indeed an invalid state.

Unfortunately I don't have the old config file, so all you have to work with is the stack trace I originally provided. It's up to you whether you want to pursue this (since there was definitely a bug somewhere) or close the issue now that a workaround was found.
