Meaning of Error Message?

[sdkid]

I was checking on a banned user with the "Track User" function.  One of the logged error messages was related to the profile for another user:

8: Undefined variable: user_info
?action=profile;u=XXX

What is this?

Bump.

Still wondering exactly what this means.  Is this an error in the profile of user xxx that pops up any time any member views that profile?  What is the error?  Is this error an indication of someone with multiple accounts?
