Crash just after launch on Sierra

Reported by Brock Brandenberg | October 2nd, 2016 @ 02:21 PM

I'm getting a repeatable crash of MailMate on Sierra that does not occur on El Capitan. It "appears" to be related to saving or writing to a local store, but I can't diagnose any further and need some tips on how to better isolate the problem for you. I have run under a second account with a not-yet-configured MailMate (meaning no IMAP accounts set up), and it does not crash, so it's related to the setup or contents in my regular user account.

I have a ton of crash logs, but they all show the crash after what appears to be an operation in OakUtilities looking for the existence of something during a save operation (below). I've triple-checked permissions on my ~/Library folder and subfolders, but I'm not sure how to troubleshoot any further from here. Looking for some tips :)

    Having done a rebuild according to some other tickets, I'm adding the ".files_to_be_written.tmp" file from my ~/Library/Application Support/MailMate folder for your reference (filename changed to unhide it).

    I'll stop with this addition, I promise, but it's an important addition... Interestingly, the crash has occurred at the same "exists" operation but with a different backtrace.

    How did you update to Sierra? It looks like you might have restored MailMate from a backup which can unfortunately leave MailMate in an inconsistent state (because MailMate cannot control the order in which files are backed up).

    I think in your case it's best if you delete the following folders and let MailMate rebuild from the servers (refetching emails):

    ~/Library/Application Support/MailMate/Database.noindex
    ~/Library/Application Support/MailMate/Messages.noindex
    ~/Library/Application Support/MailMate/Messages
    ~/Library/Application Support/MailMate/Attachments

    I'm a bit surprised though that rebuilding the database did not work. You did as described in the manual pages?

    Sorry about the inconvenience.

    In my case, I keep my user folder on a second partition and point my UNIX user to the other folder using the advanced options under Sys Prefs -> Users & Groups. So it wasn't restored, but rather "inherited" from my existing user folder. Being a Mac dev, this is the only sane way that I can keep two OS installs running simultaneously (current and beta, or beta and previous). Other than Spotlight having updated its internal format in the past and getting full rebuilds of the database when switching the startup OS, it's never posed a problem for me.

    I did a rebuild again, but because I keep all of my messages on the server now and none locally, I get a "0 messages" dialog on launch, I hit OK, and then it starts synching and crashes. I'll delete the suggested folders and try again. Quick question... "Messages" is supposed to be a symlink to "Messages.noindex", correct?

    Don't mind the inconvenience... I'm doing troubleshooting with my apps on Sierra so I know how this goes :) Something changes behavior slightly in a method in a framework or a function in a library, and voila, late night bug hunting begins :)

    Well, whad'ya know, I got a successful rebuild after deleting the folders and letting it re-fetch from the server. Actually, I just moved all four to a Desktop subfolder for safe keeping, but same effect. Thanks.

    The previous rebuild, I did according to "Manually resetting MailMate" in the help pages. First command reported that no tmp files existed, the second generated the hidden rebuild file, then I got the "0 messages" dialog when I relaunched, then boom another crash report.

    Thanks again,

    • State changed from “new” to “cantreproduce”

    Yes, Messages is a symlink depending on your Spotlight related settings in the General preferences pane.

    I'm afraid the issue was not related to upgrading to Sierra. It's probably a more general (rare) issue which MailMate does not handle gracefully.
