I can reproduce a plasmashell SIGSEGV in `FcCharSetHasChar()` via `QFontEngineMultiFontConfig` while Klipper is initializing. Opening System Settings triggers crashes regardless of the page. I removed `~/.cache/fontconfig`, rebuilt the user cache, ran `sudo fc-cache -rsv`, and rebooted, but the same plasmashell crash recurred.
Launching System Settings with `FONTCONFIG_USE_MMAP=false systemsettings` does not crash for me. My default sans font is `/usr/share/fonts/truetype/noto/NotoSans-Regular.ttf`; `fc-list` showed no fonts installed under my home directory. I had removed Chrome before these later crashes. I can provide the full backtrace if useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2168420 Title: libfontconfig: SIGSEGV in FcCharSetHasChar (rax=0xfefefefefefefefe) in Qt6 apps with a user font cache in ~/.cache/fontconfig To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/2168420/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
