[issues:#5536] musicxml2ly broken in all lilypond installers since 2.19.44

In lilypond 2.19.44 an enhanced but broken version of musicxml2ly was shipped. Every lilypond installation that was made using one of our official installers since lilypond 2.19.44 contains an unusuable musicxml2ly script.

An example: Instead of producing

 \clef "treble" \key c \major \time 4/4

musicxml2ly emits

  \clef "treble" \^@k^@e^@y^@ ^@c^@ ^@\^@m^@a^@j^@o^@r^@ \time 4/4

with the python 2.4.5 provided by all lilypond installers. (^@ here means an ASCII NUL byte)

The patch that introduced the problem was discussed in issue 4751.

After the patch was pushed Phil Holmes was the first to correctly realize that the enhanced musicxml2ly needs at least python 2.7, see https://sourceforge.net/p/testlilyissues/issues/4751/?page=1&limit=25#97dc

Although musicxml is used in GUB it is not affected because GUB uses the systems's python and not tools::python or linux-64::python as the interpreter for musicxml2ly.
