Testers needed: Crash in Lion while/after deleting notes and syncing to Simplenote

[scrod]

I'm informed that the following crash can occur after adding many notes, waiting for syncing to begin, and then deleting some of them. If anyone can reproduce this more reliably I'd appreciate your help.

You can use the build below for Simplenote synchronization on Lion: http://dl.dropbox.com/u/1886801/Notational_Velocity_2.0b4-10.7-compat.zip

Crashing on exception: fetcherForDeletingNote: got deleted note and couldn't find a key anywhere!

I'll try it out on Lion in the morning (or in a little bit if I catch a second wind).
