Based on the provided steps to reproduce, this is very likely another duplicate of
- Bug #418242 "Incorrect call to output plugins (with persistent error message) on copy"

Trigger in most cases is a custom clipboard manager (e.g. when using Xfce), or a (java-based) download manager. Other duplicates confirm the same issue when running Netbeans or OpenOffice at the same time as Inkscape.

There is no fix available at the moment - the current known workaround is e.g. to disable the clipboard monitoring of download helper apps.

Could you check whether you have any applications or applets running which actively monitor the clipboard?
