I can reliably make it swap with just one terminal (running screen over SSH) and epiphany with a dozen tabs. The tabs have a bunch of bugzilla.gnome.org pages, and some other websites. The tabs act as a TODO list, so I have had them for a while and it wasn't a problem before.

It can always be some other thing that is eating away memory. However, it seems unlikely since this happens just after opening some new tabs on a freshly booted machine.

Or I can wait for this bug to be fixed and see if it also addresses my problem. :)
