Second follow-up: mythfilldatabase crashed on the first run after the 
InnoDB conversion.  The stack trace was identical, so this strongly 
suggests the problem is not related to the specific DB engine but is a 
more generic problem.  This rather looks like a use-after-free problem 
or a thread timing issue.

Other suggestions are welcome, as otherwise a mysql is downgrade is 
probably in my near future.
