[imp] Strip Attachment not working in Horde Webmail 5.0.2 (IMP 6.0.2)

Hi,

I'm in the process of upgrading from Horde/IMP H3 to the latest versions. This is all going on a new server, built and configured from scratch: CentOS 6.3, Apache 2.2.15, PHP 5.3.3, Dovecot 2.1.1, Postfix 2.6.6.

I've successfully installed Horde Webmail 5.0 about a month ago (through pear) and then upgraded to 5.0.2 (again through pear) today. Most of it is working fine, but there's one annoying bug that I can't seem to resolve: strip attachment functionality is not working.

In 5.0, it wasn't returning a clear error message - it was actually doubling up on the attachments every time you try to delete it.

In 5.0.2, it's not working and I'm getting an actual error: An error occured (sic) while attempting to strip the attachment. This happens in both Dynamic and Basic views.

When I enable debug logging in Horde and IMP (IMAP), I get the errors below.

I've also tried the following combinations:
1. Connecting Horde 5.0.2 to my current server running H3 + Dovecot 1.0.7 - I can't strip the attachments
2. Connecting Thunderbird v17 with the new server (Dovecot 2.1.1) - I can strip the attachments
3. Connecting Horde H3 from the current server to the new server (Dovecot 2.1.1) - I can strip the attachments

So, the issue seems to be somewhere in the new version of Horde (Horde Imap Client 2.4.1).

Does anyone have any ideas about where to look for the solution to this problem?

Thanks,
Tazza
