[Bug 178274] Re: [hardy] firefox breaks on some pages with an X error

[Johan Van de Wauw]

... and they crash again:
After running:
gdb --args firefox-3.0 --sync
and putting a breakpoint on gdk_x_error() like suggested

and opening
http://www.howtoforge.com/themes/htf_glass/images/bg_header_bottom_left15.png

The program 'gecko' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 104401 error_code 11 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.)
