for both of these, the problem (i think) is that svn is trying to look
in your working copy for the file, and it's been deleted, so it can't
find it. if you give a url as the target instead of a path, it should
work. (i.e. svn log -r 1 file:///path/to/repos/b). the log command
really should be easier to use with deleted files, since you basically
have to know the reivsions it existed in to get any useful log info
about it. this is annoying when you're trying to figure out when
something was deleted for example...

out of curiosity, what file system are you running this on? we've had
weird berkeley db errors in the past that turned out to be file system
bugs.

well, either your apache logs would have something about a crash, or
you'd see your client crash (if you were accessing it via ra_local).

that shouldn't cause that kind of problem (as far as i know).
