On 1st start on a clean install (or suitably wiped akonadi configs), Kmail (or Kontact with Kmail integrated) crashes on 1st run with:

org.kde.pim.akonadicore: Failed SpecialCollectionsRequestJob::slotResult "Invalid parent"
org.kde.pim.mailcommon: "The Email program encountered a fatal error and will terminate now.\nThe error was:\nInvalid parent"

Kmail will launch and run on subsequent starts.

Requires a pristine install with NO config files or db created yet

OR

stop akonadi with 'akonadictrl stop' and do:

rm -fr ~/.local/share/akonadi* ~/.cache/akonadi* ~/.config/akonadi* ~/.config/specialmailcollectionsrc

then launch kmail.

removing ~/.config/specialmailcollectionsrc (which would not exist in pristine install) seems crucial, as leaving that in place results in no crash.
