No backend found for spell checking

[Tim Folger <tf@timfolger.net>]

Hi,

I'm running debian testing, which I upgrade every few days. After my most 
recent upgrade, spell checking no longer works in kde. In system settings > 
regional settings > spell check it says "No back end found for spell 
checking." The same message appears when I try to check the spellingn in a 
message before sending it. I'm using kmail version 5.2.3, kde plasma version 
5.6.5, and kde frameworks version 5.25.0. Has anyone else encountered this?

Thanks,

Tim
