How to repair an Eclipse/Android installation? PNG load problems in the Graphical XML editor

Question

For quite a while my Eclipse environment with the Android plug-in was running smoothly. Somewhere along the line of updates applied during the Software updates process it broke

Answer 1

I got around this problem by taking Eclipse out of Android 3.0 in the top right corner of the Graphical Layout box. I dropped the version down to Android 2.3.3 and once it finished loading this version I was in the clear. The 'button' png loaded just fine.
