Managing incoming mail filters not possible

[49MvFuNPWK]

Accessing the settings for 'Filters' is not possible since I've upgraded from 0.7.2 to 0.8.

The user interface shows the following message:

An error occured!
Unknown server error.

The log says:

"roundcube","PHP Error: Unable to connect to managesieve on imap.example.com.:2000 in /var/www/html/roundcubemail/plugins/managesieve/managesieve.php on line 294 (GET /roundcubemail/?_task=settings&_action=plugin.managesieve)"

"dbmail","[0x87dbf90] Notice:[clientbase] client_init(+167): incoming connection on [192.0.43.10:2000]"

System environment:

• CentOS release 6.3 (Final)
• httpd 2.2.15
• php 5.3.3
• Roundcube 0.8 (stable)
• PostgreSQL 9.1
• dbmail 3.0.2

These errors doesn't look like Roundcube issues. Didn't you change something more in your system?

After linking the web interface back to a previously taken copy of version 0.7.2 it works without any issue.

I just upgraded via 'installto.sh' according the documentation, without changing anything in my environment.

BTW: A friend of mine who uses the Courier IMAP server encounters problems with managesieve too (after upgrading to release 0.8).

I just remembered that I encountered the same issue some time ago.

I was/am able to fix it by replacing:

./plugins/managesieve/lib/Net/Sieve.php

by:

./plugins/managesieve/lib/Net/Sieve.php-1.3.0

It's indeed the same bug. Sieve.php-1.3.0 lacks of exactly the lines mentioned by chingson.

Could someone provide debug log so we could push Net_Sieve bug forward?

Replying to 49MvFuNPWK:

"Today 11:14:07","1","6","mail","roundcube","","1"," S: "

So, it looks like an empty string from server. Might be a server bug. Could we have a log with patched (working) version?
