It would be better to root cause the problem first.
I worked with Eric privately and tried a few things, but didn't help
so far. Most likely the workaround is also not complete before
it is fully understood. Not sure how long this will take though.
It's probably ok as a workaround for a release, but shouldn't
be considered a final fix.
