OSX <-> Ubuntu `gnome-panel --replace` causes logout and crash

[Viral]

I'm really amazed by this one, but after I've connected to my local server via the xpra client, if I restart gnome-panel --replace after it's already running, my mac explodes, as in a logout is triggered, all apps open crash, and xpra is closed. I had to reboot afterwords.

I've reproduce this twice now.

What is the server command?
Is gnome-panel forwarded individually, or is it part of a desktop session?

Does the crash still occur if you turn off opengl in the client?

xpra should never be able to crash your OS, the OS is meant to shield you from that.. a bug in your opengl drivers is the most likely explanation for the crash.

You may want to try some of the beta python3 builds you can find here: https://xpra.org/beta/macos
And also try using the native opengl bindings with xpra attach XXXX --opengl=native

Assuming that this is reproducible, we should be able to figure out the cause by running the client like this:

xpra attach XXXXX -d all >& log

By the time the process crashes, the log should contain the last few instructions before the crash, which should give us a clue.

I've had it happen via gnome-panel and gnome-session, now 3 times.

Is gnome-panel forwarded individually, or is it part of a desktop session?

I think I've seen it happen via xpra start and xpra start-desktop

Not sure, will attempt to investigate.

Absolutely, which is why I'm rather dumb founded by it. And it's not so much crashing my OS as forcing a logout and killing various apps.

Will attempt

Thanks

Still attempting to reproduce, I did however get a sig fault from just restarting gnome-panel/gnome-session/nautilus

Probably unrelated, could be related to my mac's uptime, but it was pretty low for me <4 days.

I'll try to collect more information.

Switching to betas for now, thanks

OFF TOPIC

Xpra-Python3-x86_64-2.4-r19414.dmg crashes when clicking "Load" behaviour is 100% reproducible, attempting earlier beta

[Viral]

Can reproduce "Load" crash on Xpra-Python3-x86_64-2.4-r19815.dmg as well.

Regards

The crash seems to be in the systray code, try --tray=no and / or --system-tray=no

Xpra-Python3 (..) crashes when clicking "Load" behaviour is 100% reproducible

Confirmed, moving this to #1938

As for the rest, I still cannot reproduce here.

Feel free to re-open if you have more data or a reproducible test case.
In all likelihood, this is not an xpra bug but an graphics driver bug.
