This backtrace is very clear, but I have no idea what happens here. The
panel is trying to make a connection to the GDM socket, which lies
in /var/run/gdm_socket.
It appears that this connect() call locks up. If it doesnât exist (GDM
not running), the syscall should fail immediately. Could it be that this
socket was left here after some previous GDM invocation, while it is no
longer running? This is the most obvious case for which this could
happen.
Cheers,

Bug#542712: [network-manager] NM fails to detect eth0 on multiple network cards system
Package: network-manager
Version: 0.7.1-2
Severity: serious
--- Please enter the report below this line. ---
I have two network cards eth0 and eth1 and NM, which used to work perfectly,
stopped working after an upgrade. It no more detects the eth0 interface, but
only the eth1.
Please find attached different configuration files and log messages.
A workaround to make NM work is :
aziz:~# modprobe -r ne2k_pci
aziz:~# modprobe -r b44
aziz:~# modprobe b44
but as you see, this require root privilege which make it not a really
acceptable workaround.
This bug is considered as critical as it make network not useable on my machine
without having root access.

Bug#542687: gnome-panel does not interact with mouse over VNC
Package: gnome-panel
Version: 2.20.3-5
Severity: important
I am running GNOME under VNC. For no obvious reason the panel has
recently become unresponsive. To demonstrate I make a .vnc/xstartup
containing only 'xterm &', start a vnc session, and connect to it.
>From that xterm I can start metacity (or not), and the gnome-panel.
The panel appears but doesn't respond to clicks, and if it is obscured
(by for instance restarting metacity, so titlebars appear) it does not
redraw the obscured part.
Below my system information is a backtrace from running and interrupting
under gdb, with gnome-panel-dbg installed.
What can I do to debug this?
Thanks,
Rob

in /var/run/gdm_socket.
It appears that this connect() call locks up. If it doesn’t exist (GDM

happen.
If, within my VNC session, I /etc/init.d/gdm restart, the panel
works. If I restart VNC width GDM running, the panel is frozen. I'm
far from the machine so I don't know whether GDM is working on the
physical display. It was a month ago.
I can disable GDM and get back to work, but I'm happy to provide any
extra debugging information.
