gui: clipboard error

[chlorocryptos]

Describe the issue

When copying an receiving address via clipboard (receiving addresses window - right click - copy address) an error is thrown in 'debug.log'.
Most of the time the copied address can be re-used, e.g. be inserted into other applications like an editor program, but it also occurred that the GUI crashed, while inserting the copied address into
the 'Pay To:' field of the 'Send' tab. However, while the thrown error can easily be reproduced,
the crashing of the GUI appears not to be reproducible and might be unrelated.

Steps to reproduce

1. open and sync wallet
2. open Menu -> File -> Receiving addresses
3. select arbitrary address and copy that address via right click 'Copy' of the mouse

Expected behavior

address should be copied to clipboard without errors

Actual behavior

clipboard 'copy' action throws error in debug.log:
2019-12-31 09:56:28 GUI: Data set on unsupported clipboard mode. QMimeData object will be deleted.
