emails containing attachments with extension. "txt" are not displayed in rmc when sent from roundcube same.

Good day.

Formerly RCM was installed 0.2 stable and I have worked properly. Now install 0.3.1 RCM but this throwing the following problem:

when sending emails with files with extension. "txt" attachment, RCM does not display or permit the discharge of these.

I tried from other email accounts like hotmail and attachments that arrive at the server are displayed and downloaded without any problem.
