1. Click the signature photo of this album: That's a trail??
The problem is the question marks - SP automatically translates them to dashes (or to nothing at all) in most places, but not here.

2. View any photo within that album, then click the album name ("that's a trail??") in the gallery preview on the right side of the page.
Same problem.

Looks good, thanks!

Similar/related bug:

Click the third link down in the right-margin ("Vulkan") from this page:
http://www.summitpost.org/view_object.p ... _id=396873

The problem seems to be that "mountain/rock" in the pathname for the Vulkan page is getting rewritten as mountain%2Frock in this context. Links to the Vulkan page from other places seem to be OK.
