Eric, I don't see why it would crash there. So that really leaves memory corruption which is generally means running a tool like valgrind. But the events leading up to this in myth.log are interesting. Can you reproduce this? If so please reproduce with "-v network,extra" and post both the frontend and backend logs, this may be fixable without slogging through valgrind logs.

Sorry, I can't reproduce this at this point. I don't think Ive been having that exact problem for at least some time. I'm running current trunk, and was having some unusual segfaults, so I recompiled glibc, all of QT, and kdelibs, and that now seems to have stabilized things a bit more. Thanks.

It's possible this is some memory overwriting bug that was fixed, or a problem with Eric's machine, or something else. But since it can't be reproduced anymore and we don't know of any particular changeset that fixed it I'm marking this invalid.
