Hi all,
My setup:
patben@esp-patben-lin:~$ lsb_release -rd
Description:    Ubuntu 12.04 LTS
Release:        12.04
patben@esp-patben-lin:~$ apt-cache policy evolution
evolution:
  Zainstalowana: 3.2.3-0ubuntu6
  Kandydująca:   3.2.3-0ubuntu6
  Tabela wersji:
 *** 3.2.3-0ubuntu6 0
        500 http://pl.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
        100 /var/lib/dpkg/status

Problem explanation:
While reading plain text emails in Evolution, the background colour is not white. The colour of background is the same as colour of the frame, surrounding text of email. I just hope I didn't make it too complicated :)

Expectations:
I would like to be able to set background to white, as it is in non plain text emails. Let me know if you need additional actions.

P.S. This was already reported on Evo ML:
