Thanks Federico. Unfortunately I won't be able to access this system
for two weeks. I will track this mailing list and if there is no
update I will reproduce and ping with a core.
Cheers!

Hi,
thanks for catching it :)
I'll have a look at the code as soon as I can. Do you have by any chance the
corefile of the crash?
Cheers,
Federico

I was modifying the routing blocks of the tsilo push notifications

}
If properly checked for INVITE: if (is_method("INVITE")) { /* do tsilo
stuff */ } it works.
I'm wondering whether ts_store() should/could be more defensive and
show an error like "..not the right context for ts_store().." .
Thanks for you thoughts.
Anthony
