Oh. Wasn't aware of this as I am using gthumb in XFCE not GNOME. Saw 
this behaviour in other applications and, to be honest, always 
considered it very very annoying - after all, what's the purpose in 
allowing users to set themes for their desktop if some applications 
decide to "know better"? In my environment, I usually have things set to 
a light theme with dark text because this is what is best readable / 
usable in day-to-day work. So far gthumb was pretty good here, yet at 
the moment it's extremely inconvenient because it's way too dark for my 
environment. :(

I almost exclusively use GTK applications on my desktop but I can't tell 
which one uses headerbar. From looking at things, I _suppose_ eog does 
(which also is dark but does correctly render a non-transparent header 
bar) and I think evince does too (which also has a "correct" headerbar). 
However launched from a terminal, gthumb complains that...

/usr/lib/x86_64-linux-gnu/gthumb/extensions/libimage_rotation.so: 
undefined symbol: gth_image_viewer_page_get_type


... might this be relatd to that issue?

TIA and all the best,
Kristian
