The problem seems to be related to the RFC1035 unpack. The debugging shows
that
the fqdncache function returns a broken hostname with a garbled domain.
It looks like RR->rdlength isn't updated after uncompressing the DNS answer.

There was a change in fqdncache.c from 2.5Stable4 to 2.5Stable5 which leads
to the problem appearance:

f->names[f->name_count++] = xstrndup(answers[k].rdata, answers[k].rdlength);

was: ....xtrdup(answers[k].rdata)

Our internal solution will be to disable the internal dns.
