I can't reproduce the behavior and I have also just installed buster
and unstable system in which to use qtcreator this very same week
without issues (it happens to be one of my principal tools for $job).
In none of those cases I could see a crash, so it's clearly not
happening to everyone and thus I'm lowering the severity.
It is however something we need to triage for buster.

OK, so LLVM involved.

I would expect that, yes.
I need some extra info:
- Which video card are you using?
- Please create a new user and try starting qtcreator there. Moving
out Qt creator's config is also possible, but more involved: you need
to move ~/.config/QtCreatorrc *and* ~/.config/QtProject/qtcreator/
*and* ~/.config/QtProject/QtCreator* (without qtcreator running) and
then start it.
- Have you installed any third party plugin? The crash seems to come
from loading a plugin.
Thanks for your report and your help, Lisandro.
