src/common/idle.c has old license
I wouldn't catch that if it was not for Project Hamster (http://live.gnome.org/ProjectHamster). We happen to use your file there and it should be ok as both projects are GPLv3(+). This one file still says "GPL v2 only" and effectively makes both Gajim's and Hamster's licenses invalid. Could you guys please fix the license and even better, could you give us the ability to relicense it under GPL3 or later?
Thanks a lot ;)
