[webkit-dev] WebKitGtk app memory leaks , please help

[Fedor Kryukov]

I'm not sure is this a bug or my fail )
So this is diff to GtkLauncher ( webkitgtk 1.3.5 )
http://old.nabble.com/file/p30123917/main.diff main.diff 

its very simple. So when I use it with page which reloads fast I can see
that it start to eat memory until swap is finished and app fails.

I tried to add g_object_unref( document ); and it helps, but after some
mouse movements over page app crashed and GDB shows this

Program terminated with signal 11, Segmentation fault.
