[Bug 78720] "Copy Disc" burns audio disc as data dics

[AllesMeins]

Public bug reported:

I inserted a (unprotected) audio disc in my second cd-drive. It is detected correctly as "Audio Disc". But when chosing "Copy Disc" from the context menu it just burns nonsens leaving me with something that seems to be a data disc (one 74 minutes long track with random noise). When inserting the disc in my computer it doesn't even gets recognized as an valid disc.
When using the "copy disc" tool to write the data to an image the resulting file is "CD-ROM is NOT in ISO 9660 format"
Is the "copy disc"-tool not able to copy audio discs? In that case it should warn the user and there shouldn't be an entry in the context menu. Or is it just some sort of bug?
