Description Matija Šuklje 2012-01-18 01:23:15 UTC

Application: zanshin (0.2)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r3 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:

1) open up Zanshin (doesn't matter if stand-alone or in Kontact)
2) create or edit an existing ToDo item to assign it a new context/category

3) crash

expected result:
*) no crash

This started happening (again) after I had to restart Akonadi, Kontact and Nepomuk a few times, because I had to stop a huge search in KMail.

I've reported this before and it was solved later on, but Dr.Konqui didn't find the related bug. Will do it by hand.

The crash can be reproduced every time.

I can reproduce the same by trying the same in Korganizer/Kontact *sigh* not again.

BTW, console output looks like this:

Comment 5 Matija Šuklje 2012-01-18 09:32:56 UTC

After a reboot, for some reason I cannot replicate this bug anymore (now I get plasma crashes). Which is odd, since yesterday I tested it about a dozen times and it triggered 100%.

Should I tag it as NEEDSINFO until I can reproduce it again?

Comment 6 Kevin Ottens 2012-01-18 09:46:19 UTC

Yes NEEDSINFO sounds like the better move (doing it now).

From that report so far it sounds like I wouldn't be able to reproduce at all. The cause needs to be better isolated before we can work on it. From the behavior you described so far I'd tend to suspect something further down in the stack though, but there's no way to exclude a bug in Zanshin's code.

Comment 7 Matija Šuklje 2012-01-18 10:13:56 UTC

Yeah, I suspect something lower down the stack as well, as this is just too similar to some of the other crashes I experienced in the past. Although for some reason DrKonqi doesn't seem to match them up.

Comment 8 Matija Šuklje 2013-05-27 08:13:01 UTC

I suspect it’s something to do with CalDAV resource in Akonadi.

Also it stopped creshing it, so the bug changed.
