I received the following warning while trying to locally attach an xpra session. Along with an error dialog I didn't know what to do about.

The session was normaly used on Win10 laptop (1366x768, see #2527), but now it was attached normally for cleanup.
I also don't know what I was supposed to do with the error dialog that appeared: Red X, 5 buttons: 'c', 'i', '*', 'cancel?', 'ok' - and a similar warning message
That's an old bug, not sure why we didn't trigger it before.
Fixed in r24946.
