Another followup: I *can* duplicate the problem. For reasons I'm not entirely certain of (yet), foomatic-db-gutenprint and foomatic-db-gimp-print don't coexist nicely. If both are installed, foomatic-configure barfs:
*** glibc detected *** double free or corruption (!prev): 0x081465d0 *** So, it looks like a bug in foomatic-configure (part of foomatic-db-engine), probably the C-based XML parsing code it uses. Chris -- Chris Lawrence - http://blog.lordsutch.com/
