--- Comment #7 from Ilija Hadzic ihadzic@research.bell-labs.com --- I have just posted a patch that may help at least prevent the crash. I have seen this bug on my end too, but I though that I locally introduced it with my own hacks. The patch does not solve the root cause (i.e. buffer double-free), but if it prevents the crash, maybe we can apply it to get people going until we find the real solution.
