bug#16395: Tab-containing lines displayed with different background?

[Jan Djärv]

Hello.

I simply can not reproduce this on any machine with any Linux 
distribution/Gtk+ version that I have.  You have to debug this yourself.

Colors are loaded in xfaces.c, load_color2.
For Gtk+ the background is also set in gtkutil.c, xg_set_widget_bg.

I suggest you do some tracing there and see what the difference is.
