This is what I see on the Terminal:
igor@IgorDellGentoo ~ $ ./fontsel
Cursor Changed
43
((PangoFcFamily*) 0xba5a40)
Cursor Changed
43
((PangoFcFamily*) 0xba5a40)
Cursor Changed
43
((PangoFcFamily*) 0xba5a40)
Cursor Changed
43
((PangoFcFamily*) 0xba5a40)
Cursor Changed
44
((PangoFcFamily*) 0xba5a80)
It initially selects "Sans" and then I select "Serif".
I'm testing with GTK+2.24 on Gentoo Linux.
Thank you.
