If it fixed the problem, no, don't worry about deleting the db files.

There is a failure mode where the db files are so corrupt that rpm can't
fix them.  When that happens, you must delete the db files and run the
"--rebuilddb".  Because you really don't know when you need to do that,
I always delete them.  In actual fact, I wrote an "SLS" (stupid little
script) that does it:

	[root@prophead ~]# ls -l /usr/local/bin/fixrpmdb
	-rwxr-xr-x 1 root root 345 Jan 22  2004 fixrpmdb

	[root@prophead ~]# cat /usr/local/bin/fixrpmdb
	#!/bin/bash
	# fixrpmdb - Clean up RPM database weirdness
	# Rick Stevens, VitalStream, Inc., 22 January 2004
	# First, delete the RPM database files since they may be
	# beyond help...
	rm -f /var/lib/rpm/__db.*
	# Now, rebuild the RPM database...
	echo -n "Rebuilding RPM database, do NOT interrupt..."
	rpm --rebuilddb
	echo "Rebuild complete"
	exit 0

Feel free to use it.
