I am curious: What are you trying to prove?
If anyone ever wants to know the reason for this fix, how is he supposed to find out?

comment:4 Changed 4 months ago by richardpl

Reason for fix is: do not follow cargo cult someone else did, with good intentions but with half broken solution.

comment:5 Changed 4 months ago by cehoyos

But how is the interested person seeing your fix supposed to find out about the samples for 05aa53dc?
