abort in gmessages.c

[Emmanuel Briot <briot act-europe fr>]

Please consider removing the two calls to abort() in gmessages.c.

Having such a radical signal prevents the application from handling it
nicely (for instance transform it into an exception for languages that
support them). As a result, the application crashes, instead of trying
to recover.

Isn't a gtk+ fatal warning enough ? The application is then responsible
to do whatever it needs to do, possible through a call to
log_set_handler


thanks
