Dennis,

Sounds reasonable.  So, I removed all lines mentioning "python" (3 or 4),
updated the database and rebooted (for good measure).  Alas, no change in
the contents or order of the "open with" list of either a python or python3
list.   Absolutily nothing ...

No.  Currently I'm getting a bit tired of this guessing game, and instead
want to find/have information.  Sorry.

The contents of those files (in the "text" folder) get generated by updating
the mime database.   Hence the actual info must be somewhere else.   Where ?
Your guess is as good as mine I'm afraid.

And those weights ?   Those /could/ have something to do with the ordering
in the "open with" list.  But again, thats just guessing (already tried
googeling for it).   And thats apart of how they get determined, 'cos its
certainly not in the xml mimetype definition file.

Lets hope that I will look differently at it tomorrow ...
