We are using Plone 4.1.2, and are having problem doing a copy and paste of a view in Zope Management Interface's plone_skins' plone_content. We get this error message:
Thank you very much in anticipation.
You are here: Home › portal_skins › plone_content
We’re sorry, but there seems to be an error…
Here is the full error message:

The error message you posted is an archaic one from the deep depths of Zope, but it is clear in your case. You are trying to copy something into a place that doesn't support copying.
Most skin layer folders in the ZMI reflect a filesystem directory on your disk. They are not showing you ZODB persisted objects, so you cannot add or remove items there through the ZMI.
If you want to copy a skin item for customization, use the 'customize' button at the bottom of their view to create a persistent copy in the ZODB, usually in the special custom folder, which you can then alter. Or you can find the file on the filesystem and make a copy there (into your own skins layer folder, for example).
