Comment 1 Grégory Oestreicher 2016-02-06 23:37:26 UTC

Is this still happening with the latest release? I see that, according to the number (4.89.0), it must be a beta.

Comment 2 David Yentzen 2016-02-07 02:35:55 UTC

Yes, I am still experiencing this crash. Sometimes more often than others but usually about once an hour.

Comment 3 Grégory Oestreicher 2016-02-07 13:22:24 UTC

OK, do you have the KDE Applications version you're using? Something like 15.08 or 15.12.

Comment 4 David Yentzen 2016-02-07 13:31:06 UTC

KDE Applications version 15.08.2 with Plasma 5.5.3 - Netrunner 17 is the distro.

Comment 5 Grégory Oestreicher 2016-02-07 13:38:33 UTC

Looks like a dup of #354994, merging both.

So it's crashing on a debug statement but I doubt that it's relevant. It would crash some lines after as the same function is called.

In akonadiconsole can you check that all collections in the resource have a remote identifier? From the "Browser" tab, right click on the collection (including the resource), select "Properties" and the remote identifier is in the last tab ("Internals").

*** This bug has been marked as a duplicate of bug 354994 ***

Comment 6 David Yentzen 2016-02-07 13:52:01 UTC

Ok. The next time it crashes I'll check. Now that it's merged, do I need to do anything( changed status)? [new to bug reporting]

Comment 7 Grégory Oestreicher 2016-02-07 14:27:25 UTC

No need for you to do anything about the status. Now if you want to add information though could you use the bug this one was merged with? It's https://bugs.kde.org/show_bug.cgi?id=354994 and you've been added automatically to the list of recipients.

Also to get the remote identifier you don't need to wait for the crash, you can check any time you want in akonadiconsole.
