Description Don Scorgie 2006-11-04 19:52:36 UTC 
My panel was killed.  On reload, the keyboard indicator applet didn't come up, instead deciding to crash.  Tried reloading and it didn't help.  Tried killing the panel again, and very bad things happened (it got stuck loading the gswitchit applet and the panel froze).

Unfortunately, the stack trace does not show the line numbers. Would you be able to build gnome-applets with debug info?

I am interested in these lines:

-dbg package installed.

If you're interested, I have "United Kingdom", "Spain Catalan variant with middle-dot L", "Iran Pro" and "Japan" layouts in the list.  Removing "Japan" seems to stop the crash.
