wxPython App closes on CentOS 6.5 (Seg fault)

Hi,

I have a GUI app that is written using wx. When I run it on CentOS 6.5, the following error messages are displayed and the app closes:

(python:10096): Pango-WARNING **: shaping failure, expect ugly output. shape-engine=‘BasicEngineFc’, font=‘DejaVu Sans 10.9990234375’, text=’'

(python:10096): Pango-CRITICAL **: pango_layout_get_line_count: assertion `layout != NULL’ failed

(python:10096): Gdk-CRITICAL **: IA__gdk_draw_layout: assertion `PANGO_IS_LAYOUT (layout)’ failed

Segmentation fault

I checked if this was a font issue, but the font is installed on the system.

I use an idle thread in my application.

Could some let me know what the problem may be in this case? Thank you!
