Bug#628969: [python-gtk2] frequent glibc crashes

[Brent S. Elmer Ph.D.]

Package: python-gtk2
Version: 2.24.0-1
Severity: normal

--- Please enter the report below this line. ---
I have been starting to get glibc errors lately in a python-gtk application.  Usually it has been a *** glibc detected *** ... double free with no backtrace.
This time it is a corrupted double-linked list with a backtrace.  It doesn't seem to be reproducible with any particular pattern.
It seems to be more random.

*** glibc detected *** /usr/bin/python2.6: corrupted double-linked list: 0xb158f170 ***
