[Dovecot] Crashes with 2.2.4 setup that worked perfectly with 2.2.2 (.2.3 also crashes)

[Trever L. Adams]

I am not sure how to get the symbols necessary, however the following is
the backtrace (this is Fedora 19 latest everything):

Jul  8 03:23:02 MX dovecot: auth: Fatal: block_alloc(2147483648): Out of

Any help would be greatly appreciated.

Thank you,
