texstudio segfaults after recent update

This is all I see in dmesg (I tried starting texstudio several times):

Segmentation faults are always either a hardware fault or a software bug. What did you update since it was last working? What backtrace do you get when it crashes?

Although removing a virtual should not matter here, I will reiterate the oft-posted advice that you should use emerge --depclean, not emerge --unmerge, to remove packages. Forced-unmerge relies on the administrator not making a bad decision about what to remove. A poor choice can easily break the system.

Recent update switched texstudio from Qt5 to Qt6. So you are probably guessing right that it is Qt related

I've had it working with the Qt6 version, though. Like I said, it worked up until the `emerge world` I did on the 10th. So while it might have been Qt-related, it's not simply from switching to using Qt6.

This is the end of the stacktrace:

Try removing (or renaming) the config and see if anything changes

i.e. ~/.config/texstudio/

(because it shows up in the stack trace and old settings may be upsetting the new thing)

OK, I've built texstudio so that gdb can run it.

No, that does not help. run ran until a breakpoint. You set a breakpoint on main, so the program stopped before doing anything of consequence. Run it without a breakpoint. You want output like:

Hi Hu,

I'll post outputs below. However, I also renamed ~/.config/texstudio/ to ~/.config/texstudio.old/, and now it starts. And from there I tried replacing the newly generated texstudio.ini with the old one, and it segfaulted.

When I run gdb without a breakpoint, I get this:

arrgh, I have another question.

So, after starting texstudio with an empty config, it runs, but now it can't compile documents because it can't find 'luatexja-fontspec.sty'. This file is located at '~/path/tex-local/texlive/texmf-dist/tex/luatex/luatexja/addons/luatexja-fontspec.sty'.

How do I make it so my newly running texstudio can find this?

Also, now the "Open File" dialogue is this hideous bright color scheme. How do I fix that so it follows the WM's dark color scheme?

Cheers,
