[magick-users] unable to get type metrics

[Timo Kirst]

Hi again,

this post I published on the Nabble forum. It took very long until I
received the confirmation, that it was published on this mailinglist
but at least I received it.
I was just wondering that no answer at all was posted to my questions.
That might be ok if nobody knows a hint for the issues but to make
sure that this is the case and it was not due to the fact that it
somehow was not published correctly, I just quote the message below.

So could at least give somebody just a sort of "lifesign" that this
message is published correctly?

Thanks in advance.

Regards,

Timo Kirst
