Comment 1 FiNeX 2008-02-21 10:08:22 UTC
It crash because korganizer is crashing at startup.
You shouldn't be able to start korganizer as a standalone application, right?

Reopening, still happening in trunk.
Comment 6 Thomas McGuire 2009-01-03 15:17:14 UTC
Ok, for me it is happening when I use the Akonadi resource (doesn't happen if I use the normal resources).
I have sub-todos, if that plays a role here.
Can be triggered always be switching from summary to calendar.

FWIW, I'm also using the Akonadi resource and I also have some (completed) sub-todos.

*** Bug 179689 has been marked as a duplicate of this bug. ***
Comment 9 Thomas McGuire 2009-01-05 10:30:53 UTC
Reassigning to the Akonadi kresource bridge, as this doesn't happen with other resources.
Comment 10 Thomas McGuire 2009-01-05 10:33:19 UTC
Adding Kevin to the CC list.
Kevin, please look at the valgrind output in comment #6, to me it seems that the Akonadi resource does some double-delete of the todos, and this probably triggers the paint event crash later on.
Comment 11 Dario Andres 2009-01-17 00:20:16 UTC
Isn't the original backtrace fixed by the 0256-fix-recursive-backingstore-sync-crash.diff patch ? (I though it was...)
Comment 12 Kevin Krammer 2009-02-08 14:40:53 UTC
SVN commit 923208 by krake:

Using nested event loops to achieve synchronous call behavior while doing Akonadi jobs has created way to many issues due to unexpected re-entrancy.

This is basically backport of a series of changes in trunk which replace this form of blocking with real blocking of the caller and delegating the Akonadi job execution to a worker thread.

This should fix all the bugs this is sent to. If they remain with 4.2.1 once it is released, please re-open.

Darío, in case I missed some of the eventloop related bugs, please feel free to close them as well.
