Original report

i'm working in a city vegetation with instances vertex. I take a sphere and i use its vertex for duplicate a simple leave. i add to the sphere a displace modifier for make noisier the distribution. And when i try to go to the UV editing Blender Crash.

Sorry if i do something wrong, it's my first bug report. Thanks a lot! Bug report.blend

While i was reporting this i discovered that the crash don't happen when i have the single leave selected (the leave that is child of the sphere)

This crashes if the instancer is hidden from viewport, so easier steps to reproduce are:
