[arch-general] Strange pacman problem with conflicting dependencies

[Arthur Titeica]

Hi

On a machine with a less frequent updating schedule (~once a month) I receive 
the following when doing pacman -Suy

----------------->8-----------------
# pacman -Suy
:: Synchronizing package databases...
 testing is up to date
 core is up to date

error: unresolvable package conflicts detected

:: virtualbox-host-modules and virtualbox-modules are in conflict
----------------->8-----------------

I didn't have any problems with the virtualbox replacements on another machine 
with daily updates.

If necessary the debug pacman log may be found at http://pastebin.com/9nh5tp9t

Thanks.
