The last crashes don't happen on CyanogemMod.
Comment 2 Chris Lord [:cwiiis] 2012-03-19 04:49:09 PDT
This would happen if mBuffer disappeared before the task was run - which I think may be possible as I don't cancel the task on destruction (bad me :(). I'll cook up a patch that takes care of this and addresses a couple of tidying issues I missed.

Cancel progressive upload task on buffer destruction

The main function of this patch is to cancel the progressive upload task on buffer destruction, but this also does some minor tidy-up and adds a little robustness.
