Had to reboot to solve it (I tried using the bugreport feature at that time but it didn't work).
Reminded me of the i9100 RIL crashes

RILs and modems are paired, if you are using the RIL optimized for .48 it's not going to work as well for .33, doesn't mean it won't work at all, but there may be issues, CM comes with the .48 RIL therefore you should use the .48 modem, if you aren't doing that and you have bugs that's not a CM problem.
He's welcome to disagree with me on this, but if he were to report this issue to JIRA it would be closed for this reason, so that's why I keep saying it here when he reports it.
