Using the 3.4 beta AppImage, I get a crash any timne I try to open a menu via the keyboard mnemonic (eg, Alt+F for File menu). I thought at first it might be something unique to me ChromeOS/Linux hybrid environment, but Peter says he can reproduce too.

However, I cannot reproduce using a more recent nightly build AppImage, nor can I reproduce using my own build from master. And even in 3.4 beta, all works as expected opening the menu by clicking it.

Our best guess right now is this relates to the Telemetry module, since it would be enabled in 3.4 beta but not in development builds. Dmitri suspects a null pointer in the shortcut handling (since mnemonics are trapped by Qt and not seen by MuseScore).
