Recreation steps:

1) Create a Simple project.
2) Create a Folder in the project, name it 'mydir'.
3) Create a text file in the 'mydir' folder, name it 'file1'.  The Text Editor
for 'file1' is opened automatically and given focus.
4) Create a text file in the 'mydir' folder, name it 'file2'.  The Text Editor
for 'file2' is opened automatically and given focus.
5) Exit Eclipse.
6) Launch Eclipse again, and the editors for 'file1' and 'file2' are opened
automatically.  The editor for 'file2' has focus.
7) In the Navigator view, right click on the 'mydir' folder and select Delete.
8) In the Confirm Delete dialog, click Yes to delete 'mydir'.
9) The editor for 'file2' is closed successfully, but then the "Unable to
Restore Editor" dialog appears, with the message, "Unable to open editors".  
10) Clicking on the Advanced tab of the exception dialog shows the message
"Unable to create editor: file1".  
11) Click OK to close the dialog.  Usually, the editor for 'file2' is closed.

The following message appears in Configuration Details:
"!MESSAGE Unable to restore editor - createElement returned null for input
element factory: org.eclipse.ui.part.FileEditorInputFactory"

Also, it doesn't seem to matter what kind of project (Simple, Java, etc.) or
what type of editor (Text, Java, third-party, etc.) is involved to generate the
error.  However, editors other than the Text Editor seem to remain open on
'file2', after step 8.

In the above scenario, if 'file1' is given focus before step 7, the error does
not occur.
