There might be cases where we can't properly start the thread, e.g. when out of memory (as it seems to happen on low-end 32bit versions of Firefox). We now avoid the crash.
The data should be safely stored on disk and on the next upload it will try again (and hopefully succeed).
Still needs some testing. Not sure yet how to inject a thread start failure.
