ok
Thanks for you're explanation and your work

Just wondering why not make it a requirement in cmake if it will be built anyway

solved
other than the /home/user ,
I had another mounted filesystem as root and a user directory with music files in it.
not trash directory like
.Trash
or
.Trash-1000
at the root of this file system
strawberry can not create another .trash directory at root of this filesytem
(trash directory need to be at root of filesytem
then can not use it then do not delete
and do not use the "desktop user one" the one for /home/user

solution:
do not have top mounted directory as root but as strawberry user
or create a
.Trash
directory with good permission for strawberry user at the root dir of the mounted filesytem

Delete from disk does delete file only when file is playing.
this is odd
I expect it to delete any file
playing or not ,
in database or not
when file is in playlist...
Am I wrong to assume this?

using linux
strawberry 1.0.22, 1.0.23

@smeatheringham
not the same behaviour (or I misunderstood you)
this way
I can see what has been played.
I can see what will be played

A shuffle button to shuffle in one go the whole active playlist.
addition to existing right click on playlist then select shuffle playlist

not the same as
