[TxMt] RegisterProcess failed (error = -50)

[hadley wickham]

When I try to use the TM command line tool, I get the following error:

RegisterProcess failed (error = -50)
Abort trap

I've tried deleting the launch services cache (as detailed in the
release notes) but that doesn't seem to make any difference.  Using
the growlnotify command line tool gives me the same error, so I wonder
if there's something wrong at my end.

Any help would be much appreicated,
