[Dune] GmshReader in parallel applications

Hi fellow Duners,

Has anyone out there ever successfully used the Dune::GmshReader in 
*parallel* executions ?

I'm using release 2.3 of all the core modules, and the following code 
snippet works great in serial (./myprog):

   Dune::GridPtr<GridType> gridPtr( Dune::GmshReader<GridType>::read( 
gridfile, true, false ) );

but hangs in parallel runs (mpiexec -np 2 myprog) ...

Any suggestions would be most welcome.

Thanks,

Alastair
