So far you have been asserting that over and over again, but haven't
answered Obata's question of how to reproduce it.

You haven't provided any real evidence to support this.

I completely disagree on this. Most cases of "this is an harmless error,
let's silently ignore it" have created head aches in the past. Broken
dependencies are a good example of this. Magic workarounds without a
clear understanding of the code and the (supposed) bugs are just bogus.
They do not help.
