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.
