I can reproduce this in yakkety with the following command:
yelp ghelp://usr/share/doc/pspp/pspp.xml#ONEWAY

seems to be an issue with the uri parsing

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Vlad Orlov (monsta)]

Yes, it's reproducible with uri that ends with a page section name (after '#' sign).
