Which version of 1.0 are you using? Best try with 1.2.0 or later, there
were some fixes that made it work (at least for some people).

If you still have these problems with that version, try setting
G_DEBUG=fatal_warnings in the environment and get a backtrace of those
criticals/warnings with a debugger.
