plugins/destroy-stream-twice.html and plugins/npruntime/npruntime.html take out the following error: The program '<unknown>' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 208 error_code 2 request_code 53 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 --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.) Both of them has an embed tag with width:0 and height:0 attributes. It came out that the X server does not accept a pixmap with (0,0) dimensions so we need to handle this as a special case.
plugins/object-embed-plugin-scripting.html is also affected.
