Details - I have my DUNE application on a parallel and a serial machine and discover that the two versions handle relative paths different. The problem is, that the mpihandler changes the path, where a my programm is executed. I modified the  dune-common/common/test/mpihelpertest.cc to show you the problem (code attatched).
If you compile this and change the directory, say to common/exprtmpl and execute: ../test/mpihelpertest you get:

/home/patrick/dune/dune-common/common
/home/patrick/dune/dune-common/common/test

I think this strange behaviour is a bug. If it's not, it would be nice if somebody can explain it to me.

Thanks a lot, with best regars, Patrick
