I don't have any easy way to test this, since the current versions in 
Debian are all based on Go 1.  On the other hand I guess it doesn't make
things worse.  Anybody have any objections to this patch?

In the long run we have to decide what to do about these bindings. Seb
(or anyone else) are you interested in porting them to Go 1 and
maintaining them?  Otherwise it may be time to deprecate them.
