Merged fix from gimp-1-2:

2001-01-09  Sven Neumann  <sven@gimp.org>

	Merged fix from gimp-1-2:

	* app/gimpbrushlist.c
	* app/gradient.c
	* app/palette.c
	* app/patterns.c: check for NULL pointers before doing strcmp on
	default names. The default names for brushes, patterns, ... can
	be NULL if they were not set in a readable gimprc file.

	* app/gimprc.c: warn the user if the systemwide gimprc couldn't be
	read.
