Plugin Greenshot not working anymore

I am using Greenshot.org to copy-paste screenshots into tickets and comments of tickets. Since the last update (last friday?) this is not working anymore.

1. Make screenshot with Greenshot
2. Copy to Clipboard (Greenshot message 'Copied to Clipboard appears)
3. Go to ticket in Jira, and use Ctrl+V
4. Nothing happens

PS;

• It is still possible to paste the screenshot to any other applications, so it seems to be a bug at the Jira side, not Greenshot side
• Greenshot plugin is present, although I do not use the 'Upload to Jira' functionality, but just copy-paste)
