[Bug 1293252] Re: gnome-panel crashed with signal 5 in _XReply()


Is there anything I can do to help troubleshoot this?  I purchased
Kerbal Space Program "early access" on Steam this morning, and gnome-
panel crashes with this error whenever I try to run the game.  This does
not happen with the KSP demo, only the full version.  A web search
suggests this may affect any game that uses the Unity engine, not just

While KSP is running, any attempt to start up gnome-panel results in an
immediate crash with this error output:

(gnome-panel:7495): Gdk-ERROR **: The program 'gnome-panel' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 2047 error_code 8 request_code 62 (core protocol) minor_code 0)
  (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

I use "gnome-session-flashback" as my desktop environment on Ubuntu
14.10.  The default desktop environment does not seem to be affected by
this (I tried in a Guest session), but even in the Guest session you can
still reproduce the error by attempting to execute "gnome-panel" in a
terminal window while KSP is running.

If I install libcairo2-dbg and run gnome-panel with the GDK_SYNCHRONIZE
environment variable, the crash occurs on line 905 of
cairo-1.13.0~20140204/src/cairo-xlib-surface-shm.c when
_cairo_xlib_surface_update_shm calls XCopyArea().  According to the
XCopyArea docs at www.x.org, "The drawables must have the same root and
depth, or a BadMatch error results."  Unfortunately I am not versed in X
programming, so I don't know what to try next.
