1. Open score.
2. Open Mixer.
3. Open Synthesiser.
4. Load soundfont (if there isn't one).
5. Delete soundfont.
6. Add another soundfont.
7. In Mixer, change the sound.

Result: Crash.

DIscussion: You can close the mixer at some point to refreshing it, before changing the sound (avoiding crash).

Using MuseScore 2.0 Nightly Build (4367) - Mac 10.6.7.

Can confirm similar issue (1) on Windows 7 with latest Nightly build (bb0298e). Also found a work-around (2) that suggests to me this may be related to an uninitialized configuration parameter.

1) Crashes 100% reliably (for me). Assumes you have more than one soundfont installed (see 3).
Load score.
Start playback.
View->Synthesizer
Pick any soundfont below top one & click Up button
Crash (see below for details)

2) To inoculate (now #1 will not cause crash)
Load score.
Before anything else, View->Synthesizer & click on any soundfont under top one & move it Up.
Close Synthesizer dialog.
Start playback.
View->Synthesizer
Pick any soundfont below top one & click Up button
NO crash and it works as expected.

Hi

Crashes are critical :).

Thank you, I was not aware that crashes are critical. Can you test if the workaround works on your Mac? Thanks.
