(Sorry about not using send-pr, but installing GNATS on my machine
for non-FreeBSD purposes seems to have screwed up send-pr.)
I'm trying to rip my CDs. The program I'm using to get the header info
(to query CDDB) works the first n times I run it (where n >= 1),
but at some point the open fails with "Invalid argument". It works again the
next time I reboot. Sounds like a bug to me. Anyone have a clue?
The program (courtesy of Daniel O'Connor, doconnor@gsoft.com.au), is the
following:

The output of the program looks like:
% cddb-id /dev/cd0a
cddb-id: Failed to open /dev/cd0a, reason: Invalid argument
As stated before, the program works just fine at least once before it gets
into this state.
