Error in unknown conditions: TypeError: Can't pickle objects in acquisition wrappers

[rafaelbco]

Sometimes in my production site I see messages in the Zope event log stating that collective.logbook was unable to save an entry in the persistent error log, due to a TypeError: Can't pickle objects in acquisition wrappers (full message bellow).

I was not able to figure out the exact conditions for this to occur. However I figured out how to fix the issue and I'll send a PR.

@ramonski would please make a new release? Also, I forgot to add an entry to the changelog.

[ramonski]

Of course @rafaelbco! However, I would like to fix that email formatting issue as well https://github.com/collective/collective.logbook/issues/16, but not sure when I find some time for it. In the meantime I added you to PyPI as well. If you have some time, go ahead and do the 0.9.1 release. Otherwise I'll do it as soon as possible;)

I've just made the release to PyPI. Thanks!
