Gecko + Flash problem

[benoit]

Hi Ubuntu users,

I'm experiencing a strange problem with all my gecko browsers. Each
time, the browser loads a page with a flash content, it suddenly crashes
with this output:


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 104 error_code 8 request_code 147 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.)


Any idea?


Benoit.
