Comment 6 for bug 23875

(In reply to comment #5)
> Here is the console message resulting from looking up www.acer.fr in firefox:
> $ firefox
> The program 'Gecko' received an X Window System error.
> This probably reflects a bug in the program.
> The error was 'BadMatch (invalid parameter attributes)'.
> (Details: serial 121 error_code 8 request_code 146 minor_code 3)
> (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 --sync command line
> option to change this behavior. You can then get a meaningful
> backtrace from your debugger if you break on the gdk_x_error() function.)
