This anomaly happens when you attempt to log URLs that contain front slashes on the value side of a name value pair. Blablablablabla? Basically, that means if there are front slashes (/) appearing after a question mark (?) in the URL, you won't be able to log the URL in full. Meaning, if the URL looks something like this:

http://www.example.com/story.php?name=/will/not/work

You won't be able to bookmark it.

We're looking into this issue at the moment. Keep those fingers crossed.
