Taxonmony/forum: cannot link to the forum name

Issue Summary

I wish to create a nice breadcrumb for forum navigation, so made a Breadcrumb for Taxonomy Vocabulary=Forums, tith Titles=
Forum
[node:taxonomy-forums:name]
Paths=
forums/forum
[node:taxonomy-forums:url]

But when visiting the forum node, the second last part of the path (corresponding to [node:taxonomy-forums:url]) above, the link points to http://SERVERNAME/SERVERNAME/PATH

Note how servername is doubled.
I also tried setting the second path to:
forums/forum/[node:taxonomy-forums:name]
but this wont work when there are spaces in [node:taxonomy-forums:name]
