I like the explanation that Giuseppe provides. I will add that any time you get an error message that includes a traceback then you are experiencing a software bug. And the solution to that is to upgrade the software.
I note that your router is running 12.4(1) and at this point that is pretty old code. So you would be well advised to look into getting a more recent version of code for your router.
If the error just started happening recently, it may be possible that you could get some short term relief by rebooting the router. That might allow the router to get around whatever has been triggering the error. But the long term solution should be a code upgrade.
