#5 Exception when deleting document

[Anonymous]

I get this error when deleting a document:

Unhandled exception caught in event loop.
Reason:
org.eclipse.ui.internal.dialogs.WelcomeEditorInput

This error only appears when I also have a 'Welcome'
tab open (which is the default on a new installation).

When I close the Welcome item the delete works properly.

Reopen a Welcome item (Help-Welcome-Eclipse Platform,
for example) and the delete crashes again.

Since it is easy to avoid by closing the Welcome tab,
it is not critical; but could be confusing for new users.

Here is the info and stack trace from the Configuration
Details screen:
