Sean, I have encountered the same problem. The problem lies in how command-line arguments are parsed.
Have a look at the following webpage https://csd.vpac.org/twiki/bin/view/Tech/ParallelDebugging#Using_valgrind_with_MPICH_to_che which gives instructions on getting valgrind to work with mpich. The upshot is that you will have to create a mpirun_dbg.valgrind shell script that parses the command line arguments correctly. This may require a little monkeying around with the script, like stripping of quotes and such.
