Thanks for taking the time to report this bug.
Unfortunately, that stack trace is missing some elements that will help a lot to solve the problem, so it will be hard for the developers to fix that crash. Can you get us a stack trace with debugging symbols? Please see http://live.gnome.org/GettingTraces for more information on how to do so and reopen this bug or report a new one. Thanks in advance!

after install the package gnome-dbg and some other debug packages the stacktrace is as follows. But there are still a lot of "No symbol table info available." messages in there. Hope it did clear some things up.

Please install the gnome-panel, glib and gtk+ debug packages to get a useful stack trace. Thanks!

well. i installed around 130mb worth of -dbg packages and still dont get any significant change in my stack trace. seems like i wont be able to supply
sufficient information so the only thing left to do is leaving a howto
on reproducing the behaviour:

step 1: click on the clock applet in the panel to make it pop up.
step 2: click on the big analog clock at the bottom. (the corresponding location on the map will blink 3 times)
step 3: while the location is still blinking repeat step 1 in order to make the popped up clock applet disappear

this results in a crash of the gnome-panel.

note: if you execute step 3 after it blinked 3 times then the gnome-panel wont crash.


sorry that i cant be of any more help. :(

Ah, that's bug 519493. It's fixed in gnome-panel 2.22.1.
