I thought I'd throw my hat into the ring and risk upgrading to 14.10 beta (using GNOME here) via dist-upgrade. All seems well, except for this:

Rebuilding /usr/share/applications/bamf-2.index...
Can't locate File/Find.pm in @INC (you may need to install the File::Find module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .) at -e line 2.
So it looks like something is wrong here. Any ideas?
