In any case, I agree: I consider myself fairly adept at solving issues like these, but I would have used a different set of tools—probably strace and gdb. There are quite a few tools in this post that I’ll need to check out. I know “programmer solves weird crash in everyday app” doesn’t make headlines, but I wish we’d see more of these posts.
I mean, I can eventually get redirecting stdout to /dev/null, but not having logs from stderr anywhere is asking for troubles... I guess.
I would guess that could show some kind of open() and "not found" or other syscalls on file descriptors like stderr just before crashing and that could be good leads or where into look next.
