error with python/sgmltools in sid

[Kenward Vaughan <kaynjay@igalaxy.net>]

I'm running Lyx 1.1.16fix1, using sgmltools under the DocBook class to
translate my sgml class document to other formats.  Regardless of what I do
to view or export the text, I get an error stating:

File "/usr/lib/sgml/misc/sgmltools/python/utils.py", 
                                     line 250, in _searchInCat

(I put in the return to keep things within normal column limits.)  

Does anyone know what the problem is with this?  Is there more information I
could provide to help?
