Summary: snmptable segfaults if returned content contains : character

Initial Comment:
When generating smtptable results, if any of the results contain a : within the data \
that's returned and no further . is found after that :, a segfault is caused.


name_p: ':virtualserverNumber.0'
name_p: ':virtualserverName."hotelmap.com"'
name_p: ':virtualserverName."internalsite"'
name_p: ':virtualserverName."livesite SSL"'
name_p: ':virtualserverName."Mysql Cluster"'
name_p: ':virtualserverName."londonmonthly"'
name_p: ':virtualserverName."londonmarketing"'
name_p: ':80"'
Segmentation fault

As you can see, in the line preceeding the Segfault, the returned data is along the \
lines of name:80 (in this case signifying that it's a port80 vserver).  snmptable \
(and I assume some other tools that I've experienced segfaults with) reads from the \
last : presented, and then crashes when it cannot find a period.

The attached patch does resolve this behavior, however, will return bad data cases \
where there's extra colons present.  Obviously, the desired behavior would be to \
throw an error if it cannot find a ., as opposed to segfaulting.
