I need the packages for my project pybik [1]. Thanks to your work, I
had a quick and painless transition to GTK3.

When i created this patch, I got a segmentation fault without the
zero-terminated=1 when I run my Python test script [attachment].
But it seams it was a bug (maybe 674271 ? [2]) in pygobject 3.2.0 and
fixed in 3.2.2, With the update meanwhile the segmentation fault is
gone. So maybe this zero-terminated=1 should be removed.
Btw, are you interested in Python examples in your git tree? They
demonstrate the usage of g-i, as bindings like python-gtkglext1 are
not needed any more.
