Dear all, This bug is still present in the current Debian bookworm.

This does seem like a user feedback problem for upstream. Shouldn't 'convert' be expected to give either a warning or an error to the user? The fact that it works in one case out of the two in the above example favours a warning rather than an error. Cheers Boud
