Description pah06 2004-05-25 14:05:39 UTC 
Epiphany occasionally crashes when closing (so far only popup) windows, caused
by a null pointer somewhere deep in the Epiphany/Mozilla interaction. The
following is a GDB log, showing something strange occuring between frames 3 and
4, though this might just be some kind of stack corruption.

I am using patch h3 from http://www.dsl.uow.edu.au/~harvey/code_epiphany.html,
though I don't think it is causing the problem.
