That didn't work for me, I get an boost::interprocess::interprocess_exception: what() with permission denied on creating a new game. I don't know why vcmi would try to interact with other processes, but it seems you could have done something else to make it work? Did not try "chown -R user:users /opt/vcmi/" though.

What boost version do you have installed? 1.38 or 1.42? I feel like some of my crashes might be related to the old 1.38 version I have installed. I figured it would at least run with 1.38 after spending quite a few hours porting 1.42 to Maemo... lol
Finally it might be of some use though?
