Hi, I have encountered both "behaviour" and "behavior" in xfdesktop's pot file in the master branch. This also happens to differentiate two otherwise identical strings: ./settings/xfce-backdrop-settings.desktop.in.h (line 2) "Set desktop background and menu and icon behaviour" ../settings/xfdesktop-settings-ui.glade.h (line 25) "Set desktop background and menu and icon behavior" Thanks.
Sorry, the bug's title should have been "Behavior versus behaviour"... Fixed.
Thanks, pushed to master in: http://git.xfce.org/xfce/xfdesktop/commit/?id=86e63808af48184d18e6f3a1a643886d3a614c0e
Thank you!
