For a brief moment, a ghost window with "Search - Dolphin" written across the title/window bar will appear for a moment before disappearing. The crash is reported by system notification before the ghost window appears. The crash can be reproduced every time. ~~~ABOUT SYSTEM~~~ Operating System: KDE neon 5.20 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 Kernel Version: 5.4.0-60-generic OS Type: 64-bit Processors: 12 × Intel® Xeon® CPU X5660 @ 2.80GHz Memory: 7.8 GiB of RAM Graphics Processor: GeForce GTX 1650/PCIe/SSE2 Application: dolphin (20.12.0) Qt Version: 5.15.2 Frameworks Version: 5.77.0 Operating System: Linux 5.4.0-60-generic x86_64 Windowing system: X11 Distribution: KDE neon User Edition 5.20 -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault [New LWP 91810] [New LWP 91811] [New LWP 91812] [New LWP 91813] [New LWP 91814] [New LWP 91815] [New LWP 91816] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". 0x00007f5bba174aff in __GI___poll (fds=0x7ffef2dfbf68, nfds=1, timeout=1000) at ../sysdeps/unix/sysv/linux/poll.c:29 [Current thread is 1 (Thread 0x7f5bb30278c0 (LWP 91808))] Thread 8 (Thread 0x7f5b9f65e700 (LWP 91816)): #0 0x00007f5bb5a7a33d in g_mutex_lock () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #1 0x00007f5bb5a2c73a in g_main_context_prepare () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #2 0x00007f5bb5a2d0db in ??
