Original GitHub issue: https://github.com/modoboa/modoboa/issues/547

Originally assigned to: @tonioo on GitHub.

Condition: the html composer is enabled. (If the text editor is enabled, no issue).

Create a new message.

Leave the body empty.

Send the message.

The message can't be sent, we get following backtrace on the server, but we don't get any error displayed in the GUI: the send button stays grey and action never ends.

backtrace:

It seems you mixed two different stack traces... I'm not able to reproduce this issue, it works just fine for me.
Have you tried to reproduce it ?
