I know there aren't many differences, but there were locking issues until very recently and I suspect some cases have been missed. An unclean build is always a possibility, but I built 1.3.0 from a clean tarball, both on Linux and Solaris and in both cases I get the problem. Since it's a standard release build, I don't get much info in the backtrace but here is a hint:
