Package: ip2host
Version: 0.09-3
ip2host as distributed generates lots of useless errors like so:
Use of uninitialized value in gethostbyaddr at /usr/bin/ip2host line
118, <GEN49> line 4.
Use of uninitialized value in gethostbyaddr at /usr/bin/ip2host line
118, <GEN23> line 15.
Use of uninitialized value in gethostbyaddr at /usr/bin/ip2host line
118, <GEN63> line 40.
Use of uninitialized value in gethostbyaddr at /usr/bin/ip2host line
118, <GEN37> line 27.
These are caused by IPs in the logs for which there is no PTR record.
The following patch solves the problem.
