Race condition when deleting multiple attachments

[Ingo Klöcker]

Hi,

when deleting a second attachment quickly after the first one, Akonadi runs 
into a problem:
org.kde.pim.akonadiserver: Invalid attempt to modify the remoteID for item 
1071444 from "272" to "271"
org.kde.pim.akonadiserver: Error while handling command ModifyItems on 
connection MessageViewer-43686032 (0x7fe56c4fe110)

I guess the problem is that the modification of the payload after the deletion 
of the first attachment did not yet make the roundtrip KMail -> Akonadi -> 
IMAP server -> Akonadi -> KMail and therefore KMail/Akonadi uses the old 
remoteID for the modification of the payload after the deletion of the second 
attachment.

Any ideas, how to avoid this problem? Would it be sufficient to wait for the 
first Akonadi::ItemModifyJob to finish? Or do I need to wait until the 
remoteID is updated? What about offline mode?

Regards,
Ingo
