Comment 34 for bug 418135

I've edited the patch to use g_set_error instead of g_set_error_literal (simply replacing the function since the arguments seems to already be in the right format).
Since I have minimal knowledge about the actual code involved in this I can only confirm that it works with no immediate regressions on an i386 virtualbox instance.

Yet another debdiff attached, and testing packages available in my ppa.
