It's not a permission thing. I can commit just fine (usually).
Actually, it crashes more often during read operations, then writes.
I've used both subversion binary packages & compiled it via src.rpm so
library missmatch issues shouldn't be an issue.
Honestly, as long as it's working as a standalone daemon and it
doesn't start crashing on me, I really have better things to do then
re-compile with debug and get a core dump. Obviously, if the problem
comes back then I'll see about compiling again.
