Description Heiko Tietze 2023-09-04 08:41:20 UTC 
Switching to fonts crashes the application.

On pc Debian x86-64 with master sources updated today, I could reproduce this with kf5 rendering (not with gtk3 or gen renderings)
Comment 2 Julien Nabet 2023-09-04 15:22:55 UTC 
Michael: thought you might be interested in this one since it concerns accessibility + kf5 rendering.
Comment 3 Michael Weghorn 2023-09-04 17:30:03 UTC 
Same on Windows when NVDA is running (but not without):

> Assertion failed: GetChildCount() == 4 || pWindowImpl->mbInDispose, file C:/tools/cygwin/home/user/development/git/libreoffice-WORKTREE/vcl/source/window/layout.cxx, line 1928
> Assertion failed: GetChildCount() == 4 || pWindowImpl->mbInDispose, file C:/tools/cygwin/home/user/development/git/libreoffice-WORKTREE/vcl/source/window/layout.cxx, line 1928
> Assertion failed: GetChildCount() == 2 || pWindowImpl->mbInDispose, file C:/tools/cygwin/home/user/development/git/libreoffice-WORKTREE/vcl/source/window/layout.cxx, line 1558

Interestingly, it works fine when the "Tools" -> "Options" dialog already initially opens on the "Fonts" page (e.g. because that has been saved as the last open page when having it opened before without NVDA running).
