Thread:Extension talk:SubPageList/Using Slash / in a page name

In my example a user created a page with a slash inside its name: "Connect RS232 over TCP/IP" When i call my subpage-list i get the error "Page "Connect RS232 over TCP" does not exist". So it's pretty clear that the page name gets cutoff after the slash. Here's the parameters that i've used: What could be the problem here? is this a bug or can it be circumvented?
