Bug#953363: gimp: file dialogues use black font on black background

[Heinrich Schuchardt]

The problem only occurs with the pre-selected 'Dark' color scheme.

I tried to pre-select the 'System' color scheme in file
/etc/gimp/2.0/gimprc (after deleting my personnel gimprc) but this
setting was not taken into account.

I assume file /usr/share/gimp/2.0/themes/Dark/gtkrc has to be changed to
use white as foreground color in file dialogues.

Best regards

Heinrich
