Application: krunner (5.12.5) Qt Version: 5.10.0 Frameworks Version: 5.46.0 Operating System: Linux 4.13.0-41-generic x86_64 Distribution: KDE neon User Edition 5.12 -- Information about the crash: - What I was doing when the application crashed: Attempting to open krunner with alt-F2 - Unusual behavior I noticed: krunner immediately crashed. It not fails to open - alt-F2 returns no response. Backtrace shows a segfault. I had restarted plasmashell just prior to the krunner crash, as the shell appeared to be crashing - icons all disappeared from the Panel, replaced by empty white blocks. This has happened numerous times over the past few days. -- Backtrace: Application: krunner (krunner), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Reported using DrKonqi
Created attachment 112722 [details] New crash information added by DrKonqi krunner (5.12.5) using Qt 5.10.0 - What I was doing when the application crashed: Listening to a podcast using VLC. - Unusual behavior I noticed: The icons on the main panel were suddenly replaced with large empty blocks and all panel functionalty ceased (it had crashed, in other words). I attempted to open Krunner with alt-F2 to restart plasma, which did open. However, upon beginning to type in the input field it crashed. This is exactly what happened yesterday (see above). I am attaching this to demonstrate that this is a reocurring issue and to provide a further backtrace which may hopefully be of some help. -- Backtrace (Reduced): #6 0x00007f60355dd3d5 in std::__atomic_base<QMutexData*>::compare_exchange_strong (__m2=std::memory_order_acquire, __m1=std::memory_order_acquire, __p2=<optimized out>, __p1=@0x7ffeca3958d0: 0x0, this=0x7f600df37a10 <vtable for Plasma::RunnerManager+40>) at /usr/include/c++/5/bits/atomic_base.h:752 #7 std::atomic<QMutexData*>::compare_exchange_strong (__m2=std::memory_order_acquire, __m1=std::memory_order_acquire, __p2=<optimized out>, __p1=@0x7ffeca3958d0: 0x0, this=0x7f600df37a10 <vtable for Plasma::RunnerManager+40>) at /usr/include/c++/5/atomic:462 #8 QAtomicOps<QMutexData*>::testAndSetAcquire<QMutexData*> (currentValue=0x0, newValue=<optimized out>, expectedValue=0x0, _q_value=...) at ../../include/QtCore/../../src/corelib/arch/qatomic_cxx11.h:290 #9 QBasicAtomicPointer<QMutexData>::testAndSetAcquire (newValue=<optimized out>, expectedValue=0x0, this=0x7f600df37a10 <vtable for Plasma::RunnerManager+40>) at ../../include/QtCore/../../src/corelib/thread/qbasicatomic.h:253 #10 QBasicMutex::fastTryLock (this=0x7f600df37a10 <vtable for Plasma::RunnerManager+40>) at thread/qmutex.h:101
