Re: Gtk2::TreePath broken on Debian?

[Matthew Braid <ptkperl mdb id au>]

I thought paths were safe to carry around between changes, but iters
were the things that lasted only a short time?

Also, this code was working perfectly on FreeBSD, just not on Debian.
Did a rule about the life of a path change between the versions I
have? I'll have to see if the path within the foreach sub has the same
issues.

It turns out there's a whole heap of other errors going on in my newer
Debian version of Gtk2 that never occured on the older FreeBSD
version, some of which make no sense (latest is Gtk2::TreeStore->clear
sometimes silently die-ing - I just _love_ 'sometimes' errors....), so
at this point with so much affected code we're actually considering
just switching back.
