Description Frederic Crozat 2005-05-12 15:25:29 UTC

Distribution/Version: Mandriva Linux cooker

using gamin 0.1.0 :

if I start gamin in pollonly mode, when opening menu in gnome-panel (which
creates a lot of monitors), I get the following crash :

Poll: file is new

Comment 1 Frederic Crozat 2005-05-12 15:40:36 UTC

ok, it seems to be caused by crash in gnome-panel on the other side of the pipe :

Program received signal SIGSEGV, Segmentation fault.
