This is because XML catalog in gnustep-base-common does something like 
this in postinst:
| update-xmlcatalog --add --type public --id "-//GNUstep//DTD gsdoc 0.6.5//EN" --package gnustep-base-common --local /usr/share/xml/gnustep/gsdoc-0_6_5.dtd

The parameter for --local is supposed to be a catalog, not a DTD.

However, perhaps it'd reasonable thing for amara to ignore broken 
catalogs, rather than throw an exception.

Also, it'd nice if update-xmlcatalog (or dh_installcatalogs?) could do 
some sanity checks.
