Could somebody run this test program for me?

#!/usr/bin/python
from wxPython.wx import *

dc = wxMemoryDC()
font = wxFont(10, wxSWISS, wxNORMAL, wxNORMAL)
dc.SetFont(font)
textwidth, textheight = dc.GetTextExtent("%d"%0)
print textwidth, textheight


I'm getting this:


** (t.py:19052): CRITICAL **: file pango-layout.c: line 268 (pango_layout_new): assertion `context != NULL' failed

** (t.py:19052): CRITICAL **: file pango-layout.c: line 544 (pango_layout_set_font_description): assertion `layout != NULL' failed

(t.py:19052): GLib-GObject-CRITICAL **: file gobject.c: line 1579 (g_object_unref): assertion `G_IS_OBJECT (object)' failed

These are the same asserts that Marcin noted:

I think there's a problem with wxGTK and/or wxGTK2 on Fedora Core 2.
