[Dumitrescu, Cristian]

Hi Thomas,

Yes, we can confirm that this patch is identical to one of the fixes provided by Balazs with his set of patches which were already applied.

Sorry for not seeing this patch earlier.

Thank you, Takayuki San for doing this work and sending us the patch!

Regards,
Cristian
