Hi Alexey,

Thanks for the patch. I've pushed it to the common submodule now (will
get active next time we push an update to the various modules). In
future it would be great if you could submit patches by filing a bug in
bugzilla at http://bugzilla.gnome.org, which is where we track and
review patches. Thanks!

 Cheers
