Version: 1.4.80 (using KDE 4.5.85) OS: Linux I have 3 dIMAP accounts on the same server. The first one was migrated without any errors, the other two gave an error message (something like "the migration of "accountname" to akonadi failed: resource "IMAP email server" doesn't work correctly"). I only have the translated version of that string at hand. Did the migration maybe tried to create a resource with the same name 3 times? Afterward the error message it imported everything (I saw it going through all my folders, importing thousands of mails not reporting any more errors). After the migration was finished akonadi crashed without any backtrace. When I try to start Kontact again the migration wants to start again. Reproducible: Didn't try
Ok, tried again. This time it only migrated the missing two accounts (as expected). What is strange is that I get a message "starting cache migration of folder foo", then all the messages of that folder are counted down, and later on I get "beginning import of local cache of folder foo" and all messages are counted down again. Also I can't remember seeing the first messages (which are logged for every individual folder) in the first run. That "importing local cache" only gives one line in the log, the folder things are logged for every folder alone.
Afterwards Kontact simply doesn't start. I see a kontact process around that does just nothing. When I kill it and start it again I get the migration window which says "everything already migrated", then if I click Finish nothing happens.
This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present? If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
