Backtrace with breakpoint set on gdk_x_error()
With Epiphany master, if you close the browser with Ctrl+C, about half the time you will receive this:
(epiphany:28727): Gdk-ERROR **: The program 'epiphany' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDamage (invalid Damage parameter)'.
(Details: serial 83341 error_code 149 request_code 142 (DAMAGE) minor_code 2)
(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.)
I think you can reproduce it with a stable version of Epiphany by using Ctrl+Q or the Quit app menu item.
Detailed backtrace attached.</pre>
