I’m giving WPThumb a shot for my on-demand image needs and found this same double slash issue. It doesn’t appear to be creating an issue with the image rendering, but I too am wondering why it is there? Anyone? Thx!
I decided to look into this a bit more…
The good news is that this double slash probably doesn’t affect the image getting rendered. See here:

The other bit is that I added a one-liner to the plugin to get rid of the double slash, at least in the case where it was affecting me:
Add the following so that it becomes line 305 of wpthumb.php:
if ($subdir == '/') { $subdir = ''; } // hotfix for double slash issue
Obviously this isn’t a permanent fix and it will get overwritten on the next plugin release. If a plugin author is following a long, maybe you could consider a bit of a check here for situations that would generate a double slash situation.
Or…maybe its all moot, since it seems to work fine for me with the double slashes.
Great plugin! Thx!
