Details:

Try this:

* Start psppire.
* Click on the var-sheet tab.
* Add a new variable "foo".
* Add a new varaible "bar".
* Click in variable "foo"'s name cell and type "bar".  As soon as I type the
"r", I get an assertion failure:

psppire: ../src/data/dictionary.c:653: dict_rename_var: Assertion
`!strcasecmp (var_get_name (v), new_name) || dict_lookup_var (d, new_name) ==
((void *)0)' failed.
