There are a number of reasons that Google could be putting a space in the url. The only guess I have is to thwart people that are spidering the SERP, so that they can't always get the right data. ;)
Or it could be from the webserver returning a strange response, or a spider error when the fetched the page, or a display error in their software, or...take your pick, really. I have yet to see a definitive answer myself too.

I have seen that a few times with one particular client. The 'clickable link heading' is fine - but the displayed (and unclickable) url in the search results has a space - always after a /
Its not in the 'cache' - its the URL displayed in the search results.
So - I too have seen it, i have no idea why, but you are definately not alone!
My only 'explanation' is that because Google actually found and spidered the page, and because the Google displayed 'clickable link heading' works - and because it is just the displayed URL that is 'malformed' - therefore the problem must be at Google's end. If the cause of the malformed URL was at the site's end, ie the site served a malformed URL - then Google would have indexed a 404 message... just like you get if you cut & paste the malformed link.....
