Problem with perl

Hi,

I have some problems with gtk2-perl.

Sometimes, I have this error :

Gdk:ERROR:/var/calculate/tmp/portage/x11-libs/gtk+-2.24.24/work/gtk+-2.24.24/gdk/gdkregion-generic.c:1114:miUnionNonO: assertion failed: (r->x1 < r->x2)

I try reinstall gtk2-perl but not works.

Can you help me to corerct the problem ?
