We received the following traceback twice (different UUIDs) from 4.0-0 errata66:

The code currently contains a Workaround from UCS 2.2 (which was python 2.4, I guess). → Bug #14827 / attachment 2839 [details]. The code does not work anymore with python 2.7 (msg can't be falsy, only msg.args could). Attached is a patch which fixes the displaying of that exception if the content is empty in a generic way.

The error is probably a side effect of errata 18.
As the string is empty we don't exactly know what exception was raised. But probably it is some Timeout. The attached patch also reverts that the function is called again if it fails to restore the original behavior from before errata 18.
