I have a very fresh install of lucid 10.04 64bit, fully upgraded, and with a raft of additional packages added. Amongst them is emacs (23.1+1-4ubuntu7). I habitually launch emacs from a terminal.
I just observed that when I have the GUI emacs (i.e., the result of running
emacs --nw) and I
ALT + TAB away from it, each press of
ALT + TAB results in the line
** (emacs:7690): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed
being output to my terminal window (I assume it's from the stderr of the emacs process).
This didn't happen on jaunty 9.04, for which I had the default jaunty emacs package installed.
How to fix?
