I'm on raspbian x86 and when trying to show a modal form I get:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i 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

I googled and found myself, seems that in raspbian ARM also happened
in the past

Solved hiding all form elements recursively, and then displaying them
in order again...
