Application: plasmashell (5.4.3) Qt Version: 5.5.0 Operating System: Linux 4.1.13-5-default x86_64 Distribution: "openSUSE Leap 42.1 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: I just booted. While KDE showed up everything looked normal to me as always. I looked into the Wifi overview, opened the setting but did not change to my 2nd wifinetwork. Closed wifi settings window. This time i dont understand the error message because i did it this time like several times before. But i know there is an issue with showing my batterie stats. Im counting on you guys. p.s.: new kernel improves hardware support very well. p.p.s.: sorry for this worse report. I was used to that everything works fine while booting. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

*** Bug 360103 has been marked as a duplicate of this bug. ***
Should be moved to frameworks-iconthemes then?
Maybe. Though then it would just get ignored there and it only affects plasma/krunner so it's us who have to fix it. It would also be fixed by https://codereview.qt-project.org/#/c/140446/ which is blocked because although it fixes a problem we do encounter, it doesn't also fix some hypothetical problem that we don't have \o/
krunner did not crash -- two threads are stuck in an endless cycle two threads are attempting to reshash the same KIconLoader object mAvailableIcons Qt v5.6.1 plasma5-workspace-5.7.3 17 Thread 0x7fa67f7fe700 (LWP 7391) "GlobalQueue[05]" 0x00007fa6dab99c33 in QHashData::rehash (this=0x2670c70, hint=<optimized out>) at tools/qhash.cpp:642 * 24 Thread 0x7fa67ffff700 (LWP 7398) "GlobalQueue[12]" 0x00007fa6dab99c3b in QHashData::rehash (this=0x2670c70, hint=<optimized out>) at tools/qhash.cpp:642 p this $3 = (QHashData * const) 0x2670c70 [Switching to thread 17 (Thread 0x7fa67f7fe700 (LWP 7391))] p this $4 = (QHashData * const) 0x2670c70
Seems to be the same as bug#355122. Should be fixed in Plasma 5.8 (and Frameworks 5.24), by the following commits: https://quickgit.kde.org/?p=krunner.git&a=commit&h=0314c4d16ecff82f75a97d0bf8c0ef5ed29673f3 https://quickgit.kde.org/?p=plasma-workspace.git&a=commit&h=e1692f1a21458986fac18daf6eb1d1037c9d5051 https://quickgit.kde.org/?p=plasma-desktop.git&a=commit&h=f7c41dba58ab7a50c3ff38a9f7701ab2c03b81b2 And these two are necessary in addition, to still have icons displayed in the search results: https://quickgit.kde.org/?p=milou.git&a=commit&h=5e0d799f63796741efff3ff3d780df81f03dd66f https://quickgit.kde.org/?p=plasma-desktop.git&a=commit&h=6fd35500d5cc46301f49d3fa452a51cb2c78cdae
It's not quite the same, but it is still fixed by those commits
(In reply to David Edmundson from comment #7) > It's not quite the same, but it is still fixed by those commits I meant that it seems to be the same underlying issue... ;-)
