Bug 300083

Can you please say what versions of KAlarm and KDE you are running.

Sure, I guess I got caried away with the bug form that I forgot the obvious...

KAlarm
Version 2.8.3-ak
Using KDE Development Platform 4.8.3 (4.8.3)

When you first ran this version of KAlarm, did you see any error messages? It should have attempted to import your existing alarm configuration, and if an error occurred, should have output a message.

When I first ran it post upgrade I wasn't displayed with any error messages that might indicate there was a problem.

Upon reading your comment though, I checked my .xsession-errors file and found some interesting like what I'm about to paste here.

Can this be related with the fact that by default I don't run akonadi ?

It looks as if akonadi fails to run successfully. Akonadi should start automatically when KAlarm starts, but for some reason is failing. It looks from your .xsession-errors output that it's something to do with mysqld failing, but I'm not entirely sure what the problem is. Do you have mysqld installed?

KAlarm needs to put out an error message when this happens, so that the user knows that there is a recognised problem. I'll add this in.

KAlarm will now disable the main window and display a message if Akonadi can't be started. This will be in KDE 4.8.5 (if that is released), or failing that, KDE 4.9.0.

Git commits 37458cc29f531186d7453ef955b7de330d02ecad (4.8 branch), 19610d334206a88d11ea1aaa577d02e5b8869804 (master).

Closing this bug, since KAlarm starts Akonadi when possible, but the failure of Akonadi to run in this case is outside KAlarm's control.

This fix has made it into KDE 4.8.4 after all.
