Description Adam Huffman 2008-08-09 12:02:13 EDT
Description of problem:

On my Rawhide system libvte has been segfaulting, causing gnome-terminal to crash.  It seems to be triggered by mouse selection, though the problem is intermittent.

The error in /var/log/messages:

segfault at 80260d5fe ip 0
00000312f629240 sp 00007fffa02bc050 error 4 in libvte.so.9.3.0[312f600000+128000
