[21447:21447:0706/161816.609660:FATAL:thread_restrictions.cc(38)] Check failed: false. Function marked as IO-only was called from a thread that disallows IO!  If this thread really should be allowed to make IO calls, adjust the call to base::ThreadRestrictions::SetIOAllowed() in this thread's startup.  If this task is running inside the TaskScheduler, the TaskRunner used to post it needs to have MayBlock() in its TaskTraits.
