--- Comment #5 from Ian Proudler <i...@f2s.com> ---
This may be related:
I have two monitors permanently connect. Recently (kubuntu 15.10) I have been
having problems where the main panel freezes. The icons are present but nothing
happens when you click on them. I have discovered that this can be rectified if
I disable one of the monitors and then re-enable it. In doing so krunner
crashes.
The KDE bug reporting app does not work. It will not let me select a related
bug. The saved back trace is:
Application: krunner (0.1)
Qt Version: 5.4.2
Operating System: Linux 4.2.0-21-generic x86_64
Distribution: Ubuntu 15.10
-- Information about the crash:
<In detail, tell us what you were doing when the application crashed.>
-- Backtrace:
Application: krunner (krunner), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
