Thanks for the report. I have noticed this happen to me too and think I can reproduce this locally.

[rustymagnet3000]

Yeah, me too. I see the crash consistently with 1.4.1. The alert shows fine but then crashes.

I still need to fix this, but for informations sake, the backtrace after a second invocation at the moment is:
