1. Master has been patched to cope with a situation where no spell-checker dictionary is found.

2. One reason that Balsa finds no dictionaries when built with enchant-1.6.1 seems to be that it looks for myspell/*.dic in /usr/share/myspell/dicts, while earler versions expected them to be in /usr/share/myspell/ (or at least that's where hunspell-en-0.20140811.1-9.fc27.noarch installs them).

3. Even with the patch to master, and with a symlink "sudo ln -s /usr/share/myspell/ /usr/share/myspell/dicts" to make the dictionaries visible to enchant-1.61, I *still* get a SEGV when opening a compose window. The attached program should reproduce the crash, but, when I test it, it does some of the time and not others. So I'm quite mystified by the issue :-(

Best,

Peter
