I'm on raspbian x86 and when trying to show a modal form I get:
Pango-CRITICAL **: 18:18:37.931: pango_layout_get_font_description: assertion 'PANGO_IS_LAYOUT (layout)' failed
The same form works under windows, other linux distros, mac os.
I get only a Division by Zero, where in my form there are no divisions at all.
As well I've added some 'writeln' with numbers to see where it crashes, and it never reaches OnShow method, is right in the ShowModal that it breaks.
I googled and found "Pango is a library for laying out and rendering of text, with an emphasis on internationalization.". So it must be a buggy label or something like that, a hidden label maybe?
Edit: also I get sometimes
TGtkFontCache.Add font desc added twice
