This patch misses the case where you just copy the files on the command
line [ if(optind < argc){ ... ]. It'd be even better to make the io_lock
paths symmetrical. I'll try to spin a patch for this tonight.
> See attached omfsck.out. Don't know how useful this is given the below:
It says your block bitmap thinks that there are certain blocks in use, but
when omfsck tries to visit all of the files, it can't reach these blocks.
It's an inconsistency but shouldn't be a problem other than not having that
extra space. If you have your music files backed up I'd recommend letting
omfsck fix it. Still won't fix the problem though.

Ah. Well, that sucks :) Use Troubleshooting->Rescan Music on the Karma to
rebuild it.

Nor I. Do you have write permission on /media/karma? EEXISTS may just
be garbage from fopen() trying an O_CREAT | O_EXCL on the open followed.
Might be worth using strace to see what the heck glibc is doing with
smalldb.

Nope.. the only error path I see which doesn't also spit out an error are
two allocs, one in smalldb_init. Strange. Just to be sure, you are using
the libkarma-0.0.6.tar.gz release?

Okay, what channel/server/nick? I irc a lot less than I once did but I can
try to jump on tonight.
