pcmanfm incorrectly escapes spaces in "Extract Here" with file-roller

Binary package hint: pcmanfm

On a Maverick amd64 system, I created a "/home/ek/dir name with spaces" directory and put a single file, test.tar, inside it. I navigated to this directory in pcmanfm (package version 0.9.7-1ubuntu1), right-clicked on test.tar, and clicked "Extract Here" in the contextual menu. I got a message box from file-roller, saying:

Destination folder "file:///home/ek/dir0name0with0spaces" does not exist.

Do you want to create it?

To double-check that it was pcmanfm, and not file-roller, that was incorrectly escaping spaces in the URI (replacing them with '0' characters instead of with the sequence "%20"), I opened a terminal and ran the command "ps x | grep file-roller | grep -v grep", and got:

29196 ? Sl 0:00 file-roller --extract-to file:///home/ek/dir0name0with0spaces /home/ek/dir name with spaces/test.tar

In Edit > Preferences > Advanced, changing "Archiver integration" from file-roller to xarchiver is a successful workaround to the problem, presumably since pcmanfm doesn't construct a URI when invoking xarchiver.

I am able to reproduce this bug on an i386 Maverick system (same pcmanfm package version) and an i386 Natty system (pcmanfm package version 0.9.8-1).
