Description Olexiy Avramchenko 2004-02-12 11:41:35 UTC 
gdk_x11_gc_values_to_xvalues() function has no check on GdkGCValues::font
field. This causes segfault when trying to create new gc from values with
GDK_GC_FONT mask set.

"gdk/x11/gdkgc-x11.c"
if ((mask & GDK_GC_FONT) && (values->font->type == GDK_FONT_FONT))
should be
if ((mask & GDK_GC_FONT) && (values->font != NULL) && (values->font->type
== GDK_FONT_FONT))

This affects gtk+-2.2 as well.

It is certainly invalid to set the GDK_GC_FONT mask when no font is 
contained in the values.
Comment 3 Owen Taylor 2004-02-12 15:29:15 UTC 
I'd agree, though thanks for filing this bug report.
