The messages you are observing are instances of the X front end trying
to obey an X resource setting on your system.
It is possible to associate actions with events under X Window using
resources that look something like this.
<some X resource setting>: #override \n\
~Meta ~Alt Ctrl<Key>d: delete-next-character()
This allows a developer or end user to bind certain key sequences to
actions.
Care must be taken when specifying these resources at too broad of
a scope because not all X applications support the same set of
actions.
In your instance, you're seeing how Mathematica does not understand
delete-next-character().
You may want to review X resource settings in your $HOME/.Xdefaults
file as well as any shared system files that set X resources to
locate the offending resource and limit its scope by adding
application-specific prefixes on the resource.
For more information on the function of X resources, refer to the Volume
3M of the _X Window System User's Guide_ by Valerie Quercia & Tim
O'Reilly, Chapter 11.
