I just tried wine-staging 2.12 with an old installation of Uplay and have been able to update the application and logging in also works.
Unfortunately Uplay doesn't display any text or images in the application itself, which is a different story than this bug here.
Yes, that is most likely the same as bug 43319. Until recently it worked, it broke with one of the UPlay updates.
