Thanks for the tip. The test was indeed trying to open a dialog
that didn't exist since I didn't have dictionaries installed, and
I also hadn't compiled libreoffice with dictionaries.

Adding `--with-myspell-dicts` to my 'autogen.input' helped the test
case pass. Do you think this addresses the root of the issue, or
should anything else be considered, like installing system-wide
dictionaries?
