Rafael,
This does NOT appear to be a BIND bug.  There is nothing here to 
indicate a bug in BIND. IMHO.

There is a delegation problem. There is a glue problem with 
ns1.impstat.com.ve and ns2.impstat.com.ve, which are the authoritive 
servers for avondirecto.com.ve.  Try to do this:

dig +trace ns1.impstat.com.ve

I get:
dig +trace ns1.impstat.com.ve

; <<>> DiG 9.8.1-P1 <<>> +trace ns1.impstat.com.ve

I am unable to resolve ns1.impstat.com.ve or ns2.impstat.com.ve 
reliably. Until that is fixed your ability to resolve avondirecto.com.ve 
will be unreliable.  Sometimes it works and sometimes it does not work.
