Thanks. Let's concentrate on the biggest 'definitely lost' leak only, since the
next one in the list is in a completely different league, and the large
"possibly leaks" also don't look suspicious to me at first glance.

It looks to me like these leaks come from gobject-introspection.

What's your version of gobject-introspection ? (dpkg -l gobject-introspection)

I checked the upstream git repository for diffs/commits, but didn't see
anything stick out that might explain this. But I also can't make the line
numbers match up with my versions, so maybe there's some patching going on or I
have the version range completely wrong.
