Comment 12 for bug 617079

I have just had the same problem (menus and toolbars mysteriously switched to Turkish). Reinstalling inkscape did not solve the problem. Once I had found the language option on the menu, I was able to switch back to English menus and toolbars by setting language to "English" rather than "System Default". The problem occurred while the language preference was set to "System Default", but, after fixing the problem and then setting the language preference back to "System Default", the menus remain in English. I am using Mac OS X (10.5.8), and the only language available in system preferences > international > languages is English.
