Background colour of gnubiff applet does not match certain themes

[René]

Binary package hint: gnubiff

The background colour of the applet seems to be 'hard coded' grey. I am using a dark theme but the background of the applet is painted light grey. This is not a very important bug but probably easily fixable.
