frankzig: I eventually implemented your solution since it seems correct. I'd have prefered to understand what's wrong with my original solution but it's probably better to fix the issue sooner... Thanks again for the feedback. Any enlightment appreciated about the issue :)

This one should be resolved, BTW.

Edit: my assumptions turned out to be wrong.

Thanks for the feedback and sorry for the bug (I'm the author of the translation). I've had a look and could not find where my code is failing, I'll try to examine it better and find out the problem soon. I'll let you know, sorry for the delay.
