Speicherzugriffsfehler

## I hope, you can understand this. Its german
## Please try to fix this, because this bug is awfull, and I cant work with it.
## If you have any Questions, just ask !

[Brian Crockford (keeblebrox)]

Near as I can tell speicherzugriffsfehler translates as memory access error in English--AKA a segmentation fault. I have this issue as well when editing projects with lengthy imported clips split into many slices.

Attached is an example project file that frequently results in segmentation faults.
