Not really thought about it, just used GPL-3 as a default licence.

Oh, that certainly isn't my intention. Trying to make sense of GPL's 
FAQ: https://www.gnu.org/licenses/gpl-faq.html Am I correct that Okular 
is licensed under GPLv2 /only/? If that's the case then perhaps I am not 
allowed to use GPLv3 for my fork, and should change to GPLv2 or "GPLv2 
or later".
