Please see bug #139325 for further details.
Calling in graphics. Could you please check whether the affected code is in the package (see mentioned bug)?
From what I see here, imagemagick uses the external libwmf. Feel free to disagree, please. Otherwise I'll close this bug in a couple of days.
Imagemagick doesn't include libwmf source, it uses external library. Feel free to close this bug.
I agree, thanks.
