Comment 1 Milan Crha 2011-06-29 11:35:35 UTC

It was probably some kind of use-after-free memory issue, because the code reads like this:

316	if ((flags & G_ASK_PASSWORD_NEED_PASSWORD) == 0)
317		return;
318
319	euri = e_uri_new (ms->uri->location);
320	username = euri->user;
321	password = e_passwords_get_password ("Calendar", ms->uri->location);

thus either the 'ms' or 'ms->uri' is gone when this callback is called. Without steps it's pretty hard to tell, though, and I saw no update in your downstream bug report either.

Do you have any suggestion what to do?
