Bug#451245: gtk2-engines: Warning seen: /usr/share/themes/Mist/gtk-2.0/gtkrc:6: Invalid symbolic color 'fg_color'

Hi Loïc,

I originally noticed the error running gvim, but I also see it with
gnome-theme-manager (I use KDE as my desktop but use a few gnome apps).
I tested a couple more apps at random - eog and gsynaptics - and yes,
the same error appears.

This is what happens in my terminal when I reinstall gtk2-engines and
then re-apply my fix:

tbooth at barsukas[tbooth]sudo aptitude reinstall gtk2-engines
<snip aptitude cruft>
The following packages will be REINSTALLED:

I double-checked that the 'Mist' theme is still selected - it is.  Now
on starting gvim the error is gone, and I have the right theme.  On this
machine it seems pretty clear cut: with hyphens the error appears, with
underscores it does not.  Splitting or joining the line makes no
difference.

BTW - I've not looked into the error with Glossy as I don't use that
theme and can't see an obvious problem.

The machine is running testing fully updated (or possibly a day behind
as the Oxford APT mirror is only updated overnight).

Cheers,

TIM
