Gnome Panel Freeze

[Shibu]

Binary package hint: gnome-panel

I am using Ubuntu 10.04. When I start my machine, the Gnome Panel is getting hung. The Clock, Pidgin indicator, Gmail Notify etc freeze. Then I used to 'killall gnome-panel'. Then it works fine. This bug happens very frequently, but not every time I start my machine.

Thank you taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace of the freeze following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

Pedro,

how do you run a backtrace on gnome-panel?
If I kill gnome-panel then it is automatically reloaded. I have no idea how to make a backtrace for it.

Ok,

I have found the wiki part "ask GDB to attach to a program that's already running."
But gnome-panel is already frozen right after logging in. If I kill gnome-panel it respawns automatically and runs fine from then on.
But the first run when I log in Gnome is the one that freezes. How do backtrace that before it freezes?

[Pedro Villavicencio (pedro)]

Since it's a freeze you need to attach gdb to the gnome-panel process, run the gnome-panel, check what's the PID of it (with ps) and run gdb as: gdb gnome-panel PID then get a backtrace as described on the document i've previously linked, there's also documentation on how to get a backtrace for already running processes here: https://wiki.ubuntu.com/Backtrace#Already%20running%20programs ; thanks vatbier.

Now the gnome-panel is not freezing. Its working fine. I don't know any update fixed it. The backtrace is attached here.

Pedro, thank you for your response.
But I don't understand it. The gnome-panel is frozen from the moment I log into Gnome. Is a backtrace possible on a program that is already frozen? I thought a backtrace only shows debugging code that happens after you run gdb.

Hi,

I also have this issue. It is really annoying because the clock also freezes, and a lost the time! :-/

I have noticed, until now, that this happens only when the panel is in the "not expanded" mode.
However, I will work the next days in the expanded mode to make sure this is true.
I also can reproduce this bug by initiating empathy from the panel (by the small envelop icon).
It is also easy the see what is happening with g-eyes in the panel.

Note, this is a important bug, since I have noticed it is present is the 10.10 (beta) version of Ubuntu.

Best regards.
