1. Install the e4 tools so you get the live editor.
2. Start Eclipse.
3. Point at a new workspace.
4. Alt+Shift+F9 to bring up the live editor.
5. Expand down to find the _placeholder_ of the 'Package Explorer' part.
6. Close the 'Package Explorer'.
7. You will now be in an infinite error dialog loop. You must kill Eclipse to exit.

I have a similar problem, but with Indigo (Build id: 20110916-0149), while it was working correctly on Helios.

I have a tree containing items with images.
When I remove some elements of this tree and then I call refresh on this tree (while the tree is visible), I have a crash with the following error:
