Firefox 2.0 Crash Problem

[disappearedng]

Hi everyone,
I am currently using firefox 2, which is required by Eclipse's Apatana plugin.

Unfortunately, my firefox2 crashes on a regular basis with the following message:

disappearedng@192 /usr/home/disappearedng]$ firefox
LoadPlugin: failed to initialize shared library /usr/home/disappearedng/.mozilla/plugins/libflashplayer.so [Shared object "libpthread.so.0" not found, required by "libflashplayer.so"]

The program 'gecko' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadShmSeg (invalid shared segment parameter)'.
  (Details: serial 89 error_code 179 request_code 147 minor_code 2)
  (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 what that means
