I installed the latest poi_1.2rc2 version on my Plone 3.1.5 site on Windows 2003.Now, whenever I try to change the state of an issue (e.g open -> resolve) the following error is thrown:

After the error is thrown, there's no email sent out. I noticed this error happens only for issues that have an attachment. If there's an issue without attachment there's no error in the logs and the email does gets sent out but with an empty subject line and unreadable format i.e.

I'm seeing the same thing with Poi 1.2rc2 on a CentOS 4 system with Plone 3.1.6 (I have Poi 1.2rc3, but haven't had a chance to check it yet).

See: http://groups.google.com/[…]/30bfc9bc19c64aea# and http://paste.plone.org/24825

I've been able to read the emails without trouble by simply editing out the blank line before the

It's still a problem on 1.2rc3, but I believe I have found a simple solution. Please consider applying the attached patch, which uses MailHost.secureSend() to email the MimeMessage directly, rather than converting it to a string first.

Just a quick note that I am currently busy moving to a new apartment so I have no time to look into this now. Thanks for the patch; I will test it later when I have time to see what impact it has. In my experience it can be very tricky getting emails correct, at least in the face of internationalization.

Ok, after installing the patch on a number of broken server I can confirm that it does in fact fix the problem.

I would be *really* grateful if someone could incorporate this two-line change into the released buildout ...

The unicode error is fixed in r76700. Thanks to Derek for the initial version of this fix, pointing at secureSend.

I never got the initially reported missing field error though, except sometimes in the logs so not in the browser. Is that still happening?

I see that things can still go wrong in some cases (like having Japanese characters in the sender name) when replying to an issue. I'll look at that.

When an email is sent, it works fine now, but apparently the original issue still exists. I got the attached error from a user yesterday.

Clearly he is using unicode characters in his message, and he _was_ trying to attach a file. For now, I'll just suggest he not try to do both at once.

I fixed the 'Field Missing error' that was thrown in the logs by kss: I just needed to remove the 'blurrable' class in browser/response.pt.

No responses can be added.
