Thanks for your bug/backtrace. Could you get the same with the libglib2.0-0-dbg
libgtk2.0-0-dbg packages installed?

[Ondřej Nový (onovy)]

sorry, but i can reproduce that error from now (i tried remove that dbg
packages, but no crash now :(
keyboard applet is not crashing, only modem applet (as reported in other bug)

[Ondřej Nový (onovy)]

can = can't

[Sebastien Bacher (seb128)]

I'm letting the bug as NEEDINFO for now, feel free to attach the backtrace
if/when that happens again

[Ondřej Nový (onovy)]

ok, got it!
