Trunk r17250 breaks clients ability to create windows (At least, in KDE)

[J. Max Mena]

My server is a Trunk r17252 Fedora 25 server, and my client is a trunk Fedora 25 client

I get this traceback when trying to connect with r17252:

Traceback (most recent call last):

The connection continues and I technically get a session, but no window forwarding - sound is working because I hear a "blorp" when my machine connects (no idea why, must be some default setting that got enabled on the server), so sound forwarding is working.

So, I perused the timeline and noticed that you added some threading to ensure gnome-shell will play nicely, and I run KDE, so on that hunch I rolled my client back to r17249 and it works fine. So that narrows it down to r17250.

Forgot some bits in r17250, fixed in r17253, see ticket:1350#comment:3 for details.

That's been the case for many months.
See ticket:1617#comment:2 : we play the "bell" sample to ensure the cutter element is initialized on.

Upped client and server to r17263 and it's working again.

Closing.
