The code (mapcanvas.tcl:593) is:

		# Finally put this into wind file format to use with GRASS_REGION
		regexp -nocase {^.* (\(.*\))} $parts(projection) trash end
		set parts(projection) [string trim $parts(projection) $end]

It should be checking the return value from regexp before trying to
use the match variables.
