@Cyp Thanks for your PR. Can you provide steps to trigger the crash so we can test this? |
|
It's not very reproducible — think it's only crashed 2 times so far for me — got the stack trace the second time. The steps are to open something with lots of tracks, press Ctrl+Shift+E and export the tracks. Maybe try to mess around with the GUI while it's exporting, not sure whether that's needed. Then repeat maybe a few hundred times until it crashes. |

@Cyp Understood. I can't reproduce a crash, but the change makes sense and should be safe. Merging 👍 |

…porting tracks.
Using signals/slots instead should be thread safe.
