I have a dark theme for my desktop (Xfce-dusk) and all versions of Geany I have used <= 1.31 have displayed the editor tabs, menu bar, status bar, status area, and other ui elements according to this theme. Geany 1.32 always displays with a light ui theme. The editor theme still works though, and I do not see anything unusual in the console output. Geany 1.31:  Geany 1.32: 
Xfce-dusk is probably Gtk+2 only (1.32 theme looks like Adwaita for Gtk+3).
@intact is probably right
@hacatu check which version of GTK Geany is using `menu->help->debug messages` near the top.
Ah, Xfce-dusk is indeed GTK 2 only, which is a bit surprising since it is the only built in dark theme, but Xfce 4 is still updating to GTK 3 I suppose. Installing a 3rd party theme fixed it. Thank you!
Closed #1766.
