Bug#589088: libgnomevfs2-0: gnome-vfs-daemon segfault causes gnome session to hang during login

[Jonathan Jackson]

Package: libgnomevfs2-0
Version: 1:2.22.0-5
Severity: normal

On a Debian Lenny installation that has performed well for 6+ months, gnome sessions now hang during logon for all 
system users. This is after the desktop background and panels appear, but before any desktop icons or panel 
icons/menus are visible.  KDE sessions are fine.

the last entry in ~/.xsession errors is "Initializing gnome-mount extension"

/var/log/messages indicates the following errors coinciding with the session hang:

I'm using Debian Lenny with the backports kernel 2.6.32-bpo.4-amd64 although the problem first appeared before installing 
this kernel, with linux-image-2.6-amd64 2.6.26+17+lenny1

Any suggestions for debugging welcome
