-- Information about the crash:
I was moving emails between folders on the gmail servers.  I was sorting email on on folder in to multiple other folders.  

It seemed to be ok if I moved one batch (order 20 emails), waited for that to finish and then move another batch. If I start one batch moving between folders, and then start more (one or several) batchs moving before the first finishes it seems to crash semi-reliably twice in 15 min, but not sure of the exact trigger).

The crash can be reproduced some of the time.

 -- Backtrace:
