The above error is due to a bug in 6.3.0. The bug is only triggered
when running a command which isn't recognised as a GRASS command. 
Recognised commands are those corresponding to files in the bin,
scripts and etc/gui/scripts directories, with any .exe or .bat
extension removed.

It's also possible that individual scripts have bugs which are
specific to Windows. GRASS probably doesn't get a fraction of the
testing on Windows that it does on Linux and MacOSX.
