Claus DIETRICH reported a new bug.

Summary
-------

Empty sender and messed up ContentType provided by gb.mime under Mint 21.2

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


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

I came across two bugs in gb.mime which occur when using Mint 21.2. 
They occur in V3.18.5 and the master.
The bugs don't occur under Mint 20.3!
The bugs are independent from the parsed contents (header only or complete email) and it makes no difference whether I use GTK3 or QT5.

Bug 1: The mime class returns an empty sender
Bug 2: The MimePart class returns a messed up ContentType

Details to the string returned in Bug 2:
