It still crashes while handling the data we get from the rrd_get_error()
routine.

I had a look at the rrdtool sources, and this crash doesn't make sense.
rrd_get_error() returns a static buffer, so it should be able to crash.

Most likely, it is just a memory scribble that hits part of the stack
as a result of the real error.

It's too late for me to do more about it now, but I would like to take 
a closer look at this. If you could tar up the 4.1.2p1 build directory
including the hobbitd_rrd binary and the core file and mail it to me.
I'll have a look at it in the morning when I'm a bit more awake.
