In a fresh install of LibreOffice Writer, a yes/no dialog is shown when I activate spell check.  The text of the dialog is garbled and unreadable.

The problem is resolved by installing the hunspell-en-us deb package.

Reproducible: Always

Steps to Reproduce:
1. Install LibreOffice via sudo apt-get install libreoffice on a system with Hunspell.
2. Open any document in LibreOffice Writer.
3. Start spell check by pressing F7 or by the toolbar button.
Actual Results:  
I see an unreadable dialog.  I am afraid to click yes or no because I don't know what I am saying yes to.

Expected Results:  
I see an error dialog saying no dictionaries were found. I click OK.
