Mail sending is blocked

Binary package hint: thunderbird

Hello, and thanks to all the volunteers

This bug occured to me dozens of times when I write an email with Thunderbird: when I push the button "send the message" or "Save the message", the little window which usually says "Sending mail" appears BUT keeps saying "Adjonction de..." (means "adding of..." in French).

The progression bar is still running so ThunderBird is not totally blocked.
When I click "cancel" on this window, it works (I return to the message window), but it does the same if I try to send again, or if I click on the "Save message" button.

So I have to restart ThunderBird, and retype the mail... so it is quite boring.

Sometimes, I copy/paste my email on another program, then restart ThunderBird, and copy/paste the message to ThunderBird, but even like that it doesn't work.

Last time, I had to shorten my message to be able to send it, so maybe it could be related to the length of the message ?

Regards,
Yann
