            Bug ID: 347464
           Summary: systemsettings segmentation fault when
                    installing/applying window decorations
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: flowwolf at live.com

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.6-031906-lowlatency x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I was installing window decorations and when I closed the decoration
installation window system settings crashed.
I can reproduce this bug every time.
The following themes were installed: Air-black, airglass-black-deco, chrome,
FormaN, glowglass-deco, PlasmaNext-windowdecoration-ideas,
transparent-oxygen-deco.
If I remove some of the themes from '~/.local/share/aurorae/themes/'
systemsettings won't crash. 3 or 4 themes don't cause system settings to crash,
but 7 or more.
However, the whole system freezed completely when tried to apply the chrome
theme. Only 3 themes were installed that time. The theme were automatically
applied at restart.

'lspci | grep vga' gives nothing, no discrete graphics card installed
'lspci -vnn | grep -i VGA'
 00:02.0 VGA compatible controller [0300]: Intel Corporation 82Q33 Express
Integrated Graphics Controller [8086:29d2] (rev 02) (prog-if 00 [VGA
controller])

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
