Unfortunately another correctness issue. I just wanted to browse LKML a bit and I saw lots of empty mails with no subject. I set this to grave as this may be a data loss. Reproducible: Didn't try Steps to Reproduce: I don´t know how this happened, thus I don´t know how to reproduce. I leave these no subject messages intact and do not try to delete these entries for two reasons: 1) It may help to debug whats going on here. 2) I am not sure whether deleting those may cause data loss. I will keep an eye on this and report any changes I see. Actual Results: Lots of mails like: No Subject From: To: Date: Unknown I get the following in ~/.xsession-errors when clicking on such a mail: martin@merkaba:~#130> tail -fn0 ~/.xsession-errors VirtualDesktopSwitch::currentActivityChanged QFileSystemWatcher: failed to add paths: /home/martin/.kde/share/config/activitymanager-pluginsrc AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" X Error: BadWindow (invalid Window parameter) 3 Major opcode: 2 (X_ChangeWindowAttributes) Resource id: 0x200259e AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "HEAD" AkonadiAgentServer(4890)/libakonadi Akonadi::ResourceBase::itemRetrieved: Item does not provide part "RFC822" VirtualDesktopSwitch::currentActivityChanged QFileSystemWatcher: failed to add paths: /home/martin/.kde/share/config/activitymanager-pluginsrc ^C Expected Results: All existing mails a visible and viewable completely. I use the following setup: 1) I had all mails in ~/Mail 2) I moved all recent mails from ~/Mail to a newly created BTRFS subvolume ~/.Mail so that I can snapshot it. I moved all the archived mails to ~/.Mail-Archiv, as these are mbox folders. 3) Then I let the migrator run so that it puts my account information into kmail2rc. 4) For each POP3 account I use I created an extra maildir agent pointing it at the maildir and then selecting "Synchronize All" in Akonadiconsole. Thus for my main account Lichtvoll I gave it ~/.Mail/Lichtvoll as maildir directory for example: drwx------ 1 martin martin 18 Apr 11 08:33 Lichtvoll drwx------ 1 martin martin 4106 Apr 11 17:28 .Lichtvoll.directory -rw------- 1 martin martin 4312743 Apr 11 08:33 .Lichtvoll.index -rw------- 1 martin martin 33909 Apr 11 08:33 .Lichtvoll.index.ids For local mails I created: drwx------ 1 martin martin 18 Jan 2 11:36 Lokal drwxr-xr-x 1 martin martin 528 Apr 11 09:50 .Lokal.directory and copied all the local mail folders into that. 5) I imported my filter rules back to this new setup, set inboxes for mail download to the right top level maildir directories and so on.

Please scratch that for now. I wanted to proof that my /home BTRFS is correct by scrubbing it, but got a kernel backtrace on trying so. I reported this with BTRFS kernel mailing list just now. I have no proof that anything with wrong with the filesystem, the rsync backup went just fine and it would have triggered any CRC checksum failure that may exist. Also there are no errors recorded except for these kernel backtraces neither in kern.log, nor in BTRFS error statistic. But still, until I know the filesystem is correct, feel free to postpone this :)
Closing bug as requested by reporter ("Please scratch that for now [could be due to filesystem]"). Martin, please reopen this bug if the problem persists/reappears. (I have something similar, but due to a different cause, obviously.)
