Wireshark-dev: [Wireshark-dev] Trunk not playing nicely with Ubuntu's overlay scrollbars

For the last few days, SVN builds have been crashing immediately on my
Ubuntu Quantal system due to Ubuntu's overlay scrollbars. The
backtrace is *entirely* within GTK and liboverlay-scrollbar, which
means it's either a bug in liboverlay-scrollbar (which is possible, as
this is an Ubuntu pre-release) or in the way we're setting up
scrollbars and GTK boxes and such (which is also possible, as that
area of the code has been seeing some churn).

1.8.0 as packaged in the repositories is not having any problems, so
clearly something has changed in our trunk, but we could just be
exposing a bug in liboverlay-scrollbar. I'll try and do a bisection
tomorrow, but if anyone who's been making some of the GTK changes
could shed some light, that would be appreciated.


P.S. The full backtrace, for reference:
