Comment 1 Frank Reininghaus 2016-02-15 19:17:55 UTC 
It seems that some code in QImageReader is confused by the clipboard contents. Could you try to copy some text from a text editor to the clipboard (just select text and press Ctrl+C) and check if that helps?

You are using rather outdated software, by the way, so the easiest way to fix the problem might be to upgrade to something more recent.

Closing for lack of feedback.
