[mrtg] Use of uninitialized value in hash element at /usr/bin/indexmaker line 352.

[Jakub M]

Hello again :)

I have encountered a strange error thrown out y indexmaker

Use of uninitialized value in hash element at /usr/bin/indexmaker line 352.

I tried to make a normal index, and with all cfg files works, only
with one that is from CatOS it does not work. I have no idea what may
be wrong. Have you encountered that ever?
