[Dovecot] Panic: file index-mailbox-check.c: line 75 (index_mailbox_check_add): assertion failed: (box->notify_min_interval > 0)

[Kevin Holly]

Hey guys,

i have a weird problem i'm trying to fix since 5 months now, but i
really couldn't find any explanation, why this happens and how it can be
fixed.

My client is Thunderbird, my dovecot version is 2.1.7-7 from the
official Debian repo. If you want to see my config i'll grab all the
fils together and send it to you.

This is the error i'm always getting when my client tries to get new
mails, which i want to get rid off:

I asked for this in the irc already but got no answer. I would be really
happy if someone can help me with this.

Thank you very much!
