ConflictError when using the subscription portlet

[Jan Ulrich Hasecke]

I get an error when I try to subscribe via the portlet:

The error vanishes when I deinstall LinguaPlone.

I can confirm this. I get a ConflictError even without LinguaPlone installed. (Though only one.) I forgot to remember when exactly this happens.

Do you get this ConflictError reliably with every subscription through portlet?

[Jan Ulrich Hasecke (janulrich-hasecke)]

I cannot always reproduce it.

In the meantime I got several times this error, when subscribing via portlet.

gaierror: (7, 'No address associated with nodename')

But this does not occur always.

Check your internet connection and your SMTP configuration in Plone. Remember that when you subscribe, S&D automatically sends out an email for confirmation.

While I don't have luck reproducing the ConflictError issue again, I've found out that some of our getpaid friends are having the same problem:

Jan Ulrich, when this happens again, can you try and hook in with the PDBDebugMode product (just add Products.PDBDebugMode as an egg in your buildout) and print out all variables that are in scope when the exception occurs like so:

  (Pdb) locals()

And paste the result back here? Thanks.
