bug#6885: Error message when saving a file

[luigi di lella]

Good morning.

I am using Linux. Whenever I save a file I get the following error 
message on the window which I used to open emacs:

** (emacs:1973): CRITICAL **: murrine_style_draw_box: assertion `height 
>= -1' failed

However, everything seems to be OK, the file is saved correctly. 
Nevertheless, it makes me nervous.

Could I know what it means and what should I do to suppress this message?

Thanks. Regards,
