Really?

That's the path you would get if you tried to parse a file
with UID 0, because the function that generates the filename
returns the directory if the UID is zero.

So you have something generating a "zero".  Either there's
a file called "0." in the directory, or there's a file called
"somerubbish.", where somerubbish is something which atoi
calls zero.

Check the directory and remove the bogus file.
