This is in bugzilla:

http://bugzilla.gnome.org/show_bug.cgi?id=122483

I looked into this one briefly, and I have a vague notion of why it
happens, but I'm not sure how hard it will be to fix.  While there is a
chance it will be fixed, I wouldn't count on it.  EXSLT functions are a
big can of worms, and they're not a top priority.

Standard disclaimer:  You should think long and hard before using EXSLT
functions in your stylesheets, particularly in production-level code.
