Thanks for a bug report and data. Can it be that you are missing the 'highlight' package in your environment? There was done a fix meanwhile, at the upstream bug [1], which has the same symptoms. [1] https://bugzilla.gnome.org/show_bug.cgi?id=684447
Yes, installing highlight fixes the problem. Should evolution require highlight?
Requiring highlight is one option. The upstream bug has a fix which formats the parts as plaintext, if highlight cannot be found. In other words, this is fixed upstream, part of 3.6.1.
