without type = shared there is no segfault,
I understand this config might not work (invoking imap directly) but
it should't segfault.

it was shared namespace with empty location that produced the error
so :
namespace test {
list = children
location prefix = test.
subscriptions = yes
type = shared
}
segfaults
with location is fine
