Links with - are not working

Hi,

When using the recent custom post type widget all titles containing a space in it are not working.
The widges uses the space in the link but in fact a - is used instead of a space.

So link should be:
http://www.gemeentehollandskroon.net/VluchtelingenWerk-Noordwestholland
but the widget shows:
http://www.gemeentehollandskroon.net/VluchtelingenWerk%20Noordwestholland

Greetings,
