baafucha fails to convert text, sometimes with 'Unhandled exception in listener callback' error

[doronwolf]

It's a bit random so I'm not sure when or why does it happen
but at certain times the keyboard for text conversion simply won't work
and the only remedy will be to restart 'baafucha'
in some of those cases (but not always) I've noticed the terminal will show the following error:

Unhandled exception in listener callback
