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).

On pc Debian x86-64 with master sources updated today (+ kf5 rendering), I don't reproduce this anymore.

Heiko: could you give a new try?
Comment 6 Heiko Tietze 2024-05-21 06:18:07 UTC 
No issue anymore with kf5/6, gtk3, and gen.
