Bug 350106

(In reply to Ross from comment #0)
> Application: plasmashell (5.2.2)
> 
> Qt Version: 5.4.1
> Operating System: Linux 3.19.0-22-generic x86_64
> Distribution: Ubuntu 15.04
> 
> -- Information about the crash:
> - What I was doing when the application crashed:
> Possible duplicate of now closed #345981.
> Prior to plasma crashes, update-notifier was issuing pesky messages at about
> the same frequency as the subsequent plasma crashes. I then changed the
> system helper settings via a pop-up from the update-notifier icon  to tray
> icons only and since then the crashing has occurred. Upon making pacakages
> up-to-date by manually running apt-get update/upgrade the crashes desist.
> Resetting the system helper settings to  popups only has not seemed to have
> corrected the problem.
> 
> - Custom settings of the application:
> Possible changing of notification messages settings.

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