OK, some strange things happened. I applied the patch for the locale/layout settings http://bugs.freedesktop.org/show_bug.cgi?id=19048 and now things work fine :s There have been other changes on my system but nothing that would jump out at me as being overly relevant. If I have time, I'll go back to a server without this patch and see if the problem returns. I have also updated libcompizconfig which was updated on the 26th December to a buggy build, but as I originally noticed this behaviour on the 24th December, I doubt this is actually relevant!
