When this happens, please start a new terminal session and run
gdb /usr/bin/rp3 <pid>
where "<pid>" is the process ID that you are given in the dialog
box that tells you about the crash, and then give gdb the command
bt
which will print out a backtrace.  Give us that backtrace, and we
will likely be able to figure out what went wrong.

Here are easier instructions for getting the stack trace:
  gdb /usr/bin/rp3
  r
  bt
Now paste the output into bugzilla for us, and we can look into
the problem.

Thanks,

Please try

If that doesn't fix it, then I'll need more information in order
to have any possible hope of fixing this.
