How to know which files have errors

[J.L. Blom]

Hi,
I have for several months problems with smart as it gives a whole bunch
of errors apparently related to channel-files but which and why is not
presented. The most elusive error is The first line of the whole message
set which is given below (unsupported scheme) but I can't find which
file is related to this error:

error: Unsupported scheme: ttp
error: Invalid XML file:
error:   /var/lib/smart/channels/updates-debuginfo%%

error:

/etc/cron.daily/sa_update:

Use of uninitialized value in concatenation (.) or string

_______________________________________________________________________
As smart is part of a cronjob I get these errors every day.
I have tried smart update after removing the complete channels directory
but it gave the same channels with the same errors. Apparently I do
something stupid but hopefully anybody can give me a clue.

Besides this, I wish everybody on this list a very good X-mas and a
happy 2008.
Thanks
