dbus protocol change (truncate support)

[Ross Lagerwall <rosslagerwall gmail com>]

Hi,

After a little more testing, I want to merge in the truncate support for
the various backends that I implemented at:
https://bugzilla.gnome.org/show_bug.cgi?id=573837

The only issue seems to be that it requires a minor change to the dbus
protocol which is "always painful" according to Tomas from the bug
report.

It seems like the best time to make this change would be early in the
release cycle, like now.  Is it OK to make it?

Cheers
