If I load up a bunch of releases in Picard and I haven't given it an OAuth key yet, it will ask repeatedly about whether I want to authenticate/log in now or not, to retrieve "personal data". If press no, it will pop up again and ask, if I press yes, the same. I would expect a browser window to open when pressing "yes", ,which it did do when I was running X and Picard on the same machine, but when doing X forwarded from my desktop to my laptop, nothing - it doesn't even open a browser on DISPLAY=:0.
