Description Xiaodai Wang 2016-08-02 09:04:09 UTC

Description of problem:
A crash occurs when connecting to a spice guest by ssh from fedora24 to rhel7

Version-Release number of selected component (if applicable):
spice-gtk-0.31-4.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a spice guest running on rhel7 host.
2. Prepare a fedora24 host.
3. SSH to rhel7 host from fedora24.
4. Launch virt-viewer/remote-viewer to connect to a spice guest.

Actual results:
# remote-viewer spice://127.0.0.1:5900

** (remote-viewer:10597): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-7jLRj4kWh2: Connection refused

(remote-viewer:10597): GSpice-WARNING **: PulseAudio context failed Connection refused

(remote-viewer:10597): GSpice-WARNING **: pa_context_connect() failed: Connection refused

(remote-viewer:10597): GSpice-WARNING **: pa_context_connect() failed: Connection refused
libEGL warning: DRI3: failed to query the version
libEGL warning: DRI2: failed to authenticate

(remote-viewer:10597): GSpice-CRITICAL **: egl init failed: cannot create EGL context

(remote-viewer:10597): Gdk-ERROR **: The program 'remote-viewer' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 325 error_code 1 request_code 153 (unknown) minor_code 1)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap (core dumped)


Expected results:
No crash should occur and connect to spice guest successfully.
