--- Comment #2 from Dave Malcolm <dmalcolm at redhat.com>  2009-12-15 17:57:31 EDT ---
The backtrace in comment #1 is from /usr/share/abrt/CCMainWindow.py, not from
yumex; somewhat ironically, ABRT is crashing with a SIGSEGV whilst trying to
display information about a crash inside yumex.

The ABRT SIGSEGV is happening deep inside pango; frame #10 is trying to render
textual content within GTK tree/list view, and frame #9 and below is processing
the text, trying to calculate the size it will take (in pixels).

Looking at frame #6, it looks like Pango is trying to do linebreaking on a full
gdb backtrace from yumex, a rather large string.

Reassigning from "python" to "pango" in the hope of more insight.
