Syncing the Steam library does not work in Lutris on Leap 15.5. I get the following error:

2023-07-16 17:47:05,984: Error while completing task <bound method BaseService.reload of <steam.SteamService object at 0x7f7b64cd87e0 (lutris+services+steam+SteamService at 0x557eb4432500)>>: <class 'KeyError'> 'contentstatsid'

Well, most users will only get a popup that says "contentstatsid" and notice the sync not working. But this backtrace is shown on the terminal when starting Lutris from there.

The issue has been tracked upstream as https://github.com/lutris/lutris/issues/4175 and is fixed in 0.5.10. But Leap still ships 0.5.9.

The specific commit fixing it seems to be https://github.com/lutris/lutris/commit/072e72a4aefd91101b79dd05d8ce9f100a4b6b0c.

If I manually apply the fix from the commit on my system, the issue is resolved. We might want to consider applying the patch during packaging or just upgrading the Leap version.
