SSHing (with X11 forwarding enabled) from a Precise machine to an Oneiric machine and running certain X11 forwarded programs causes a crash of the program, either immediately or on the first mouse click on that program's window.
I have seen this on two client machines (a laptop and a desktop) running the latest oneiric release, connecting to either the oneiric desktop release or oneiric server release on the server side. I have also reproduced this with two VirtualBox VMs, connected together with host-only networking and with desktop releases of Oneiric and Precise installed.
To reproduce:
- On client machine, install Precise with all updates as of 2012-03-29.
- On server machine, install Oneiric with all updates as of 2012-03-29.
- Set up host-only networking so that machines can ssh to each other.
- On client machine, "ssh -X" to the server machine. Then run an X11 application. Some applications will crash immediately or on the first mouse click on that application.
On my test VirtualBox setup, applications that always crash on first click:
- gnome-terminal
- nautilus
- aisleriot solitaire
- gnome-control-center
- file-roller
- firefox
- brasero
- gcalctool
- palimpsest
Applications that do not crash:
- Libre Office
- gimp
- banshee
- firefox
- thunderbird
Obviously, this isn't an exhaustive list, but you get the idea. When applications crash, they spew out a large error message. On my desktop machine, sshing in to an Oneiric Server install on a physical machine, the programs crash immediately without showing a window, but on my test setup with two VirtualBox VMs, you first have to click on the window to cause it to crash. Sample crash output is attched to this bug report in the crash_output.txt file.
