Comment 1 James Blackburn CLA 2011-05-26 04:25:47 EDT 
This is likely a core.resources issue:

Contains: Error moving metadata area from
C:\Work\CCS_5.1_Eclipse_Indiigo_M7\workspace_run\.metadata\.plugins\org.eclipse.core.resources\.projects\my_test_A
to
C:\Work\CCS_5.1_Eclipse_Indiigo_M7\workspace_run\.metadata\.plugins\org.eclipse.core.resources\.projects\my_test_B.
org.eclipse.core.runtime.CoreException: File already exists on disk:
C:\Work\CCS_5.1_Eclipse_Indiigo_M7\workspace_run\.metadata\.plugins\org.eclipse.core.resources\.projects\my_test_B.

Could you confirm which version of the platform you're running?
Comment 2 Alain Lee CLA 2011-05-26 10:13:21 EDT 
We are running with Indigo M7.

James were you able to reproduce he problem?

I think I've seen this exception before, but not sure how to reproduce.  AFAICS .projects/... is automatically cleaned up when the project is deleted.
Comment 5 Szymon Brandys CLA 2011-11-18 13:08:08 EST 
I managed to reproduce it using vanilla Eclipse.
1) Create a regular project
2) Add a folder and a file inside
3) Modify the file to create an entry in the history
4) Delete the project
5) Try to rename any other project using the name of the deleted one
The same problem. 

The issue is Project#deleteResource that calls clearHistory at the end. This call may try to store history on disc, see Bucket#load and Bucket#save. At the end all history files will be deleted, but the project folder in .metadata\.plugins\org.eclipse.core.resources\.projects remains. Simple inversion of workspace.getMetaArea().delete(this); and clearHistory(null); helps.
