When there are no blocks on the left of the messaging page, the messaging screen layout is messed up.

There are multiple ways to reproduce this, easiest is docking blocks:

Steps to reproduce:

1. Use theme 'more' with a background colour set
2. Login as admin
3. Go to My Profile > Messages
4. Dock any blocks on page

Expected result:

• The 'main' content area surrounds the content

Actual result:

• The main content area background doesn't cover the background.

Another way to reproduce is move the blocks to the right.

Steps to reproduce:

1. Use theme 'more' with a background colour set
2. Login as admin
3. On frontpage turn editing on
4. Go to My Profile > Messages
5. Move all blocks on left to right
6. Go to front page and turn editing off
7. Go to My Profile > Messages
