Artwork are not always shown correctly

[GoogleCodeExporter]

What steps will reproduce the problem?

The icon for pending artwork is not always removed:
1. Select internet radio
2. Select radio stations with "small" artwork.

Sometimes the artwork is not displayed even if it is downloaded properly from 
LMS:
1. Browse internet radio
2. Go back to previous screen.
3. Repeat until the issue occurs. Note this can be difficult to trigger and may 
depend on server/device. Seems to be more frequent on the emulator.

What is the expected output? What do you see instead?
