When filter value contains an URL, remove filter breaks

Nice catch @mxr576!

What do you think of replacing the colon character by a more specific character like pipe or something?

@mably, that could also work, but I did not want to touch the core logic of filtering since fixing this specific problem was quite simple and did not require any dirty workarounds.

Ok, let's merge it as is then.
