Segmenting fails if keyword is a URL

[anonymous-matomo-user]

For example, if you click "Year" for "Date Range" and then choose to display "500" keywords on the Dashboard, the following keyword is displayed (which is actually a URL) about halfway down the list:

http://forum.piwik.org/read.php?2,94978,94982#msg-94982

This is the demo URL which shows the filtering doesn't work:

Maybe that one is related to #4024

Moving bugs to our current milestone to make the backlog more realistic.
