That's odd.. really odd. You may want to fix(?) (read: upgrade) your
library that contains that.. but no, i don't believe it's a problem, unless
it's trying to write to it beforehand (soft link to a sensative file by a
malicious user could be bad).. or unless some other program is using that
temporary file and your program removes it. Try upgrading the library.. or
reinstall the library, something.
