Thanks for time you spent with this bug.

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"
  <https://bugs.launchpad.net/inkscape/+bug/418242>

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.

Wonderful,

exacly as you said. This problem was caused (in my case) by Java-based download manager.
Disabling the clipboard monitoring fnc. helps.
Thanks for the related bug link.

Thank you very much.

I confirm that Clipman extension on Xfce is causing this problem.
