hi,
yesterday I worked on my Suse Linux 10.1 with Eclipse Europa and
Qt-Installation.
Today Eclipse is not running up any more. There is a hint to look into
.../workspace/.metadata/.log.
This log-file contains a lot of text which does not help me.
some extract from it is here:

Most probably you found the PDOM index file of your project (the result
of indexing). You can delete the file safely offline. This will trigger
re-indexing the next time you start Eclipse. You can do the same in the
UI with Index > Rebuild.

Local History is stored under
..metadata/.plugins/org.eclipse.core.resources/.history
I think it is safe to delete everything below this directory.
But don't manipulating anyhting else below
..metadata/.plugins/org.eclipse.core.resources
might corrupt your workspace.

It basically depends on the plug-in which writes the information. A few
important files and folders are:
..metadata/.plugins/org.eclipse.core.runtime/.settings
Contains the workspace preference settings.
..metadata/.plugins/org.eclipse.ui.workbench/workbench.xml
Stores the Workbench UI layout.
..metadata/.plugins/org.eclipse.ui.workbench/workingsets.xml
Stores the working sets.
Many UI plug-ins store dialog settings (like size/position, default
values, etc) in a file called 'dialog_settings.xml'
