stderr output that shows the problem

THE CIRCUNSTANCES

I have an IMAP account (not MS-Exchanged based if that matters) shared between 3 client machines.

On these 3 client machines I run claws-mail as the IMAP client:

*   One has a Ubuntu Gutsy (2007) version (3.2 or 3.3 I guess) and works fine.
*   Another one has a 3.7.5 version and works fine.

*   The third one is the one causing problems running that started when I 
    switched from 3.7.5 to 3.7.6 with a Debian Squeeze update.

THE PROBLEM

On this third machine, when I log into my IMAP account after a period on which I have received lots of new emails and done some modifications (with respect to the latest successful login), I experience the following behaviour:

-  Claws-mail stays some time with a message "Scanning <account/INBOX>"
-  After this time the cached version of the INBOX is shown.
-  Previous emails (body not cached) can be accessed through IMAP
-  New emails don't show up.

Accessig from the same computer and location with an alternate IMAP client (e.g. thunderbird) works fine.

FURTHER DETAILS

I attached the stderr output message.

Other logging/debug info such as:  network log, --debug output and wireshark capture will be attached later.

I can't reproduce that at all, marking WORKSFORME. (err 4 is a stream error for libetpan)
