Bug#502513: gnome-utils: gnome-system-log segfaults when viewing syslog

Package: gnome-utils
Version: 2.20.0.1-2
Severity: grave
Justification: renders package unusable


When I ran log viewer for the first time I did not see /var/log/syslog
listed there so I went to File->Open, navigated to the needed file and
opened it. The syslog was added to the list and shown. But now every
time when I click, for example, on Xorg.0.log in the list and then come
back to syslog the application segfaults (dereferencing a NULL pointer).

GDB log:
