Description:
I'm attempting to move my current mail server setup from Gentoo to Arch. The only piece of the puzzle that is not fitting in is dspam. dspam-3.10.2-8 installed from community and also rebuilt locally from the community PKGBUILD segfaults in a way that I've only found reported once before and was resolved by rebuilding with different optimization flags. (here's the cleanest source: http://permalink.gmane.org/gmane.mail.spam.dspam.user/18954 ) Log output is: dspam[12421]: Ignoring disallowed preference 'signatureLocation' and then it segfaults. strace attached. The setup/config is exactly as is working on Gentoo, LMTP from postfix -> dspam -> dovecot-deliver.

This task depends upon
In my working dspam here are the strace lines immediately following where this one segfaults:
22279 stat("/data/mail/dspam/opt-in/domain.com/me.dspam", 0x7f3014ade5d0) = -1 ENOENT (No such file or directory)
22279 stat("/data/mail/dspam/opt-out/domain.com/me.nodspam", 0x7f3014ade5d0) = -1 ENOENT (No such file or directory)
22279 gettimeofday({1400810812, 867222}, NULL) = 0
22279 open("(null)", O_RDONLY) = -1 ENOENT (No such file or directory)
Seeing as how they don't exist on either installation, their non-existence shouldn't be causing the crash.

Ok, that was harder than it should have been.... interesting how the log output pertained to exactly the item that needed attention. For whatever reason I had to delete from the DB the preference for signatureLocation=headers
