Running 4.5.2 on Centos 4.4

I've noticed that the url zimlet appends a trailing slash to the most of the url's it converts from text to hyperlinks. Usually this is fine, unless the url contains variables and then it breaks the string.

The raw text:
www.somepage.com/Wn.asp?s=10975&k=315748

Is rendered as:
www.somepage.com/Wn.asp?s=10975&k=315748/

Resulting in error's from the webserver.
