xdg-open breaks rendered text on a terminal

What steps will reproduce the problem?
1. make some file:/// or http:// link
2. press enter upon the link

What is the expected output? What do you see instead?

Text on a terminal disappears (see attached image). Ctrl-L restores terminal 
though.

What version of the product are you using? On what operating system?

I use mate-terminal (old Gnome 2's gnome-terminal), Fedora 17, latest vim rpm, 
vimwiki-2.0.1.vba

Please provide any additional information below.

It looks like an issue of command 'silent !xdg-open ...'. When i remove 
'silent' the issue goes away. Surprisingly command

call system('xdg-open ' . shellescape(a:url) . ' &')

also fixes the issue, the riv plugin uses xdg-open this way and it seems to be 
the best way to fix this.

Cheers, Alexey.
