Arch Linux

Description:

claws-mail (3.15.1-3) freezes regularly when typing an e-mail, it seems that it is related to typing non-standard letters like ěščřžýáíé, etc. The application becomes unusable for me. I believe that it might be somehow related to the issue  FS#56588  - [gnome-subtitles] Can't launch with Enchant 2.1.2-2.

Downgrading enchant to 1.6.1-2 and downgrading claws-mail to 3.15.1-1 solves the issue.

Additional info:
* claws-mail 3.15.1-3, enchant 2.1.2-2
