Crash when editing choices in properties frame

[quipa]

When editing radio button choices, MrEd crashes when hovering from List of Choices straight to Values area and vice-versa. This crash does not happen if you move the mouse out of the small choices dialog and then enter it again in a arc like motion to the opposite area.

The following errors are printed in the REPL:

Gtk: _gtk_css_image_get_concrete_size: assertion 'default_width > 0' failed
Gtk: _gtk_css_image_get_surface: assertion 'surface_width > 0' failed
SIGSEGV MAPERR si_code 1 fault on addr 0x1c
Aborted (core dumped)```

Seems this is more general bug of the properties frame when editing choices, seem crash behaviour happens for example when editing tabs choices.

Hi Maxim, Thanks for the feedback! I don't have much time to test this this week unfortunately, but I'll keep this in my inbox. It sounds like it's a more low level bug than Racket programs, so it might have to be forwarded upstream. If you want to help, you can try replicating the bug outside of MrEd Designer and designing a minimum Racket program showing the bad behaviour. Cheers, Laurent

I also had the feeling it might come from upstream! Still learning Racket and the GUI tools, if I can figure out how to I will ;)!

Hey,

I don't see this behaviour on my current setup (Ubuntu and Racket v7.5.0.3).

Does this still happen for you?

I'll try it out sometime, haven't used MrEd-Designer in quite a while!
