email not possible

Status changed to 'Confirmed' because the bug affects multiple users.

The German error message is:
Beim Ausführen von 'xdg-email' ist ein Fehler aufgetreten.
Fehler beim Ausführen von 'xdg-email'.
Exit-Code: 2.

On the command line,

 xdg-email --attach /tmp/myfile.txt

 opens an e-mail composition dialog of Thunderbird just fine, but without attachment. So maybe this is (also?) an xdg-email bug.

with the following patch "shutter" -> "Email" works correctly on Ubuntu 14.10 again:

the first change makes sure that only the first occurrence of Exec in thunderbird's desktop file is considered: | head -n 1.
the second change is a fix for what is clearly a bug (having $browser instead of the correct variable $desktop).

Seems to be happening in Ubuntu 16.04 too.

I get this error on fully patched 16.04, when trying to e-mail shutter screen shots:

Fehler beim Ausführen von 'xdg-email'

Which translates to:

Error when executing 'xdg-email'

Debian fixed this via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=819149:

Date: Tue, 06 Dec 2016 21:53:19 +0800
Source: shutter
Binary: shutter
Architecture: source
Version: 0.93.1-1.1
Distribution: unstable

My problem fully relates to https://bugs.launchpad.net/ubuntu/+source/shutter/+bug/1469840

No need to track this here any more.

I am not sure if this a duplicate ...
The mentioned duplicate addresses "simple scan and thunderbird".
But with "simple scan and thunderbird" I do not have any problems sending files.

If I want to send any document in LibreOffice writer I can use the menu "send -> document as email" and it works flawlessly.
If I use "simple scan" and want to send a scanned file with thunderbird it works lawlessly too. (all done from the menu of the mentioned application (simple scan and LO writer)

But if I do the same in "shutter" -> "send with e-mail" I get the above mentioned error message.
So I think it does not really address thunderbird but shutter itself? I tried the newest shutter version but the problem is still there.

Sorry for my bad english.
