might explain your problem.
I thought this was resolved in 4.1, but it looks like the problem still persists
there. At least I have reports from my workplace that 4.1.6 and 4.1.7 are still
affected. I don't know if there have been any relevant changes in 4.2.
Copying Herbert and Eric for additional input.
There was a separate bug discovered by Tejun recently. You need
to apply the patches

There is another follow-up but it shouldn't make any difference
in practice.
