I can't reproduce with Nightly build 30e0623 under Windows 8.
However, if I try with a debug build (personal compilation) of 30e0623 in Windows 8, when I remove even one single instrument via Add->Instruments...->(Select and) Remove, MuseScore crashes with the following output:
Debug: MuseScore::cmd <instruments>
