Mixxx 2.3 crashes when I click on Adjust Beatgrid without loaded track

[Jörg Wartenberg]

Always reproduceable with the CI build of PR #3788 on Windows 7.

This bug is not caused by some skin button, and #3788 doesn't even touch the actual skin structure.

Please test again with the most recent 2.3 beta build.

I tested with 2.3 and Main, both localy build. The crash did not occur with Main, but with the latest 2.3 it crashed and I got this stack trace:
