Desktop.SendMail method broken on the master

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : Unknown


Description
-----------

Hi
This has already been posted to the mailing list on the 26th of Sep 2023.
Just regard it as a friendly reminder and forget it if you took care of
it already. 
The Desktop.SendMail method seems to be broken on the latest ppa master.
I tested it on my Linux Mint 20.3 Mate and Linux Mint 21.2 Cinnamon VMs
where the default email client is not opened. On other distros it opens
the client but doesn't include the attachment.
On my physical machine and with the stable V3.18.4 it works as expected.
A minimum demo app is attached which I used for testing.
Best regards
Claus
