[Epiphany] confused - debug works, non-debug doesn't

[mike <mike redtux demon co uk>]

Hi I reported bug where epi crashes on every second link (non-debug
build)

So I thought I  would be a good citizen (as  I've now tripled my HD
space) and do a full debug build of gtk/gnome, so I can do a proper
stack-trace.

only problem, after rebuilding gnome with debug on , the problem has
stopped.

The question is, anyone any idea why I should get a crash without
debugging on, but not with
