network-manager

Thanks for your bug. What version of Ubuntu do you use? Does moving icons on the desktop or opening the context menu works when that happens? Do you have anything useful to .xsession-errors about that?

The version is the beta of Dapper Drake, updated with the latest updates available as of the time it was posted.

No message appears in .xsession-errors that would identify the problem.

Does nautilus work on the desktop when that happens? Maybe you could open a command line and get a backtrace of the hang:
- gdb -p $(pidof gnome-panel)
(gdb) thread apply all bt

Nautilus is still responsive. I will supply the requested backtrace the next time the panel hangs.

I have discovered that killing the deskbar applet may kick the panel out of its unresponsive state. Thus the problem may be in part the deskbar applet. Though I believe that the panel should be sufficiently robust on its own not to become completely unresponsive when individual applets have problems.

I have the same problem on my laptop running latest Dapper. I deleted deskbar from the panel and now can login no problems, but I would like to get deskbar working.
I cleared the deskbar history, this didn't fix it.

Okay, I ran Synaptic, completely removed the package deskbar-applet (this also removed ubuntu-desktop). Then I logged out, reinstalled both packages from a text console, logged back in to Gnome, added Deskbar to the panel, and everything works fine now. I've logged out/in/restarted a few times to confirm that it no longer hangs.
It is good to have it working, but now I will never be able to find out what caused the app to hang in the first place. :(

This is the output from
  gdb $(pidof gnome-panel)
  thread apply all bt
when the panel has hung. I can confirm that killing deskbar-applet fixes the panel. For now, I have disabled the deskbar.

I have the same problem in 6.06. Some applet icons are loaded then the panels(top and bottom) both hang. Sometimes it takes many restarts to get past the hangup

For some reason the re-install routine described above only worked for a few days then started hanging again. I noticed that it only hangs with one particular user, and not another, so there may be a conflict app on the panel that is causing the trouble. Will investigate further.

Glenn: rather than restarting, you should kill the deskbar process.
Ctrl-Alt-F1 will bring up a console, log in then enter command:
ps -A | grep deskbar
... this will show you the process ID (a number), then enter command:
kill <process ID>
... then Ctrl-Alt-F7 to get back to Gnome desktop

removing deskbar-applet seems to have resolved the problem which is a pity as it is a very handy function.

do all people having that issue use deskbar-applet? Could you get a backtrace of deskbar-applet when that happens again?

Your bug lacks information we would need to investigate further. We
are now going to close the bug - please reopen if you have more
information at hand.

Sometimes after booting the network-manager icon becomes visible as the bluetooth and when you click on it you can not see the menu

Often, after waking up from sleep this specific problem.

Probably so, it just hangs during the implementation of the refresh signal, or return to work from sleep.

Please check those parts of the code.

If you need more information, I am ready to help you solve your problem.

Some new information about bug:

Some times when I start system, when clicked on network-manager icon - don't see the mobile brandboard entry in menu.
