- Can you always reproduce the crash ?
Thanks

I don't understand question, you ask me to crash again ? 
or if the crash appear each time ?

I'm not sure that append every time I save, I try now.

I'm not familiar woth bucktracking, if Korganizer crash I do bug and marke as duplicate or just paste the report here ?

I can run tests if you want, and, I can test beta version if it's usefull

thanks

Comment 4 Dario Andres 2009-08-26 18:48:45 UTC 
With my question I was referring to: if you reproduce the steps that caused the application to crash the first time, does the application crashes again ?

- The new backtrace seems a bit different, but it is also related to KIO.

Thanks
Comment 5 niko 2009-08-26 18:55:47 UTC 
If you need something tell me :)

My c/c++ level is little and old, so I can't do big job, but testing I can

For this crash, I have erase some task, all of them, And try to save.

egroupware is done through an akonadi resource now, rewritten from scratch.
