I ran strace on Yelp trying to open 
"/usr/share/gnome/help/accessx-status/C/accessx-status.xml" and to figure 
out where it fails but the results are thus far inconclusive. I speculate 
that xml2po should be called instead of Mozilla directly and that there is 
some mime registration problem, but I would need a similar trace (complete) 
from a working Yelp to compare. I would much apprechiate if someone zipped 
up one and emailed to me (preferably with -s100 at least, which takes about 
2MB in text and 100kB packed).

Here a snippet of my strace:
