Description of problem:
firefox crashes sometimes when calling urls


Version-Release number of selected component (if applicable):
firefox-1.5.0.5-7

How reproducible:
open firefox and call some urls

Steps to Reproduce:
1.start firefox 
2.call some urls
3.
  
Actual results:
firefox crashes with the following error:
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 120 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.)


Expected results:
no crash :)
