Right - this part is "expected". I should have tried build testing
libgtk3-perl with the new version, sorry about that.

This diff looks correct to me - I think it could be forwarded upstream
and/or uploaded.

...and this one is a real bug in gdk-pixbuf. I forwarded a potential fix
to upstream - will wait a little while to see what they say. I've
confirmed that after applying the patch already in this bug and that
proposed patch libgtk3-perl's autopkgtests pass again. Once it gets an
ack or if there is no reply then I'll upload to Debian.

Cheers,
