By any chance it's an encoding problem: maybe that buildslave
operates, say, in latin1, while the others in utf-8, or the other way

Unfortunately I do not have a general recipe: if you open the "darcs
changes --xml-output" with an editor, I bet that around that line you
will find either an "foreign" author name with "strange" letters, or a
patch name containing non-ASCII characters.

In the context of darcsver it is probably a waste using the
--xml-output and the minidom parser just to count the patches...

Wouldn't it be enough doing the equivalent of

  $ lasttag=$(darcs query tag | head -1)
  $ darcs changes --from-tag "$lasttag" | grep '^[^ ]' | wc -l

eventually with a smarter way of determining the "last (interesting)

BTW, I see that there's now an handy "--count" on darcs changes :-)
It's used by the darcs build process, see latest patch on darcs-users
wrt determine_release_state.pl
