What were you doing when this happened? What crashed? Plasma, or an app? Something font-related? It's the font thumbnailer crashing, because it only works on X11. Should get disabled or ported to Wayland. Happens to me too (Debian / Wayland). I can trigger it reliably by just opening a new Dolphin window or tab into ~, or when pressing F5 in this directory. Other directories don't seem to do it. It definitely does seem to coincide with thumbnail previews appearing. I do not have the "Font Files" previewer enabled in Dolphin settings (if that helps). Stack trace is always the same: Application: kdeinit5 (kdeinit5), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Can't reproduce the bug - I have only Places, Folders and Terminal panels available in Dolphin 20.07.70 and no Information panel. Was it unsatisfied dependency in my build, or it's just gone in new Dolphin versions? Found the reason: CMake Warning at CMakeLists.txt:108 (message): Baloo packages not found. They are needed for the metadata features of Dolphin (including the information panel). For what it's worth, I'm still able to reproduce this bug on Dolphin 20.08.3 / Plasma 5.20.3 as packaged by openSUSE Tumbleweed. Stacktrace is still the same — it definitely seems to just still be calling Xft functions even when not running under X11: Thread 1 (Thread 0x7fea401ec840 (LWP 17934)): [KCrash Handler] #4 0x00007fea42a96d63 in XAddExtension (dpy=dpy@entry=0x559ab935a140) at InitExt.c:73 #5 0x00007fea1a62f9ed in _XftDisplayInfoGet (dpy=0x559ab935a140, createIfNecessary=<optimized out>) at xftdpy.c:91 #6 0x00007fea1a633785 in _XftDisplayInfoGet (createIfNecessary=1, dpy=0x7ffdd2157620) at xftdpy.c:85 #7 XftFontInfoFill (dpy=dpy@entry=0x559ab935a140, pattern=pattern@entry=0x559ab9a74290, fi=fi@entry=0x7ffdd2157620) at xftfreetype.c:367 #8 0x00007fea1a633bac in XftFontOpenPattern (dpy=0x559ab935a140, pattern=0x559ab9a74290) at xftfreetype.c:1015 #9 0x00007fea208da144 in KFI::CFcEngine::queryFont() () from /usr/lib64/libkfontinstui.so.5 [... truncated ...] When I try to open .ttf font, it opens in a separate app named something like Font View which instantly closes, probably because of the same crash.
