Firefox Crashes With 'BadMatch' Error

[Unforgiven]

So, I'm running Debian Unstable, and firefox has been giving me a problem for a while. I had it fixed, but the solution no longer seems to work.

It used to be that anytime flash appeared on the page, the entire browser would crash. Eventually I noticed the thing that all the problem-causing sites had in common, did some googling and some poking around, and found an old mailing list post that suggested adding a line to /usr/bin/firefox. This worked, and all was right with the world. Here's the line:

export XLIB_SKIP_ARGB_VISUAL=1

I did a dist-upgrade this morning, and now the problem is like before, except it doesn't always crash with flash. I don't see anything common and always present really, it just seems to crash about half of the time I load a page.

Here's the error:

mike@winecellar:~$ 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 93 error_code 8 request_code 144 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.)

I've already put that line in the /usr/bin/firefox file, expecting that to solve the problem as it had before, but it didn't help. Anyone have any ideas?

Edit: Just as a apology in advance if it's needed, I posted this here rather than in the "Linux Applications" forum because I suspect it may be a debian package thing, and if nothing else, it was a apt-get dist-upgrade that started it (sort of). Apologies if this ought to be there instead, this seemed like an appropriate place to me.

do you have the composite extension enabled in your /etc/X11/xorg.conf? If yes, try disabling it... aka

Option "AllowGLXWithComposite" "false"

Well, it wasn't there at all in the file, so I added the line as you have it here. Doesn't seem to change anything.

Thanks, though.

Okay, I was just really stupid. The entry was already there, I just missed it somehow. Commenting it out did the job just fine.

Thanks for the help!
