another gdb backtrace after killing gnome-panel

[Pedro Villavicencio (pedro)]

could you please install the gnome-panel, libgtk2, libglib2, libwnck dbgsym packages? the one you submitted before is missing a few symbols there, thanks in advance.

[vlad (devvlad)]

gdb-out2

[vlad (devvlad)]

hi
do you have any news?
can i help? ssh access may help?

[P.Constantine (pconstantine)]

Same problem here, constant poll on fd=3 connected to unknown socket:

strace:

gnome-pan 3376 user 3u unix 0xef08b000 0t0 12525 socket

netstat:

unix 3 [ ] STREAM CONNECTED 12525

It stops after 1 to 3 minutes and returns to normal.

[vlad (devvlad)]

I resolved it by removing gnome at all, use xfce it has no javascript

Just to make it clear - invalid in this case means obsolete... Panel these days use GTK3 not GTK2, panel does not use libbonobo that I see in your attached files.

Thanks for your bug!
