Hey,
the Gtk port might leak a 'sub' Frame (at least a FrameView). The easy fix is 
to add a frameView->deref() in the webkitwebframe.cpp method used for 
creating subframes.
I'm working on PageCache for the Gtk+ port and I'm also taking a look at the 
reference counting of Frame's and FrameViews but I'm a bit short of time due 
learning for exams.

kind regards
