Sync windows exception on new linux install

I have a fresh install of Fiji on Ubuntu 16.04. So far its mostly working fine.

However, when I select the sync windows plugin from the Analyze->Tools menu, it generates an Exception error and does not open the control panel. The error in the window is pasted below this message.

I tried replacing the plugin included in the download with the latest version from Github, didn’t help.

Sync windows is an indispensible tool for me - would really appreciate any advice on how to fix.

Sorry for the delay in response… and unfortunately, I cannot solve this issue myself. But to start - you can file an ‘issue’ on the Sync_Win github repository. That would be your best bet to get the ball rolling on this one…
