Error when logging in

When logging in I just got this error:

    while executing
"expr {([string range [clock clicks] end-9 end] ^ $mypid) % 62}"

Replaced with updated one in tcllib.

I should add that the second issue is likely to be a side effect.
Remember: after a stack trace nothing can be trusted!
