Summary: dialog_publish deadlock

Initial Comment:
Hi,
I tried setting up v-1.6.3 with dialoginfo modules added. It worked nicely in testing environment, but then it deadlocked when given live traffic... Here's the bc of this deadlock:

Hi Stanislaw,

This is a known issue and a fix for it is currently in progress, a first
version has been committed in trunk but still some work needs to be done on
it. I will let you know when it is safe to upgrade.

Regards,
Anca
