Bug 342443

as you can reproduce all the time. could you install debug package and get a full debug backtrace please ?

Hi Laurent,
since this is my first bugreport I'm not really sure what to do.
Which debug package(s) exactly?
How to get the full debug backtrace?

"Application: Agent zur E-Mail-Filterung (akonadi_mailfilter_agent), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". [KCrash Handler] #5 0x00007fd75ddc8b08 in MailCommon::SearchRule::asString() const () from /usr/lib/libmailcommon.so.4 #6 0x00007fd75ddcbe74 in ??

it's a backtrace :)

Your distro provides debug package.
I don't know name of them on debian but perhaps there is a "-debug"

for example kdepim-debug.deb

I think I got it.
I installed akonadi-dbg and after stopping akonadi and executing akonadictl start in a terminal window I got some debug output.

It looks like filterin works in the first place, since there are thousands of searches running before it crashes.
At the end I get this message

Sorry for so many consecutive posts, but I got even more output by installing kdepim-dbg, too.

Thanks
it's the full test from this dialogbox ?

(In reply to Laurent Montel from comment #7)
> Thanks

yes, that's all.

 Could you give me the exact filter config that you use
(filter name etc.)
I need to reproduce it.

Or you can export specific filter as text so I can see which filter you use
thanks

Unfortunately I am not any longer using kmail.
I remember that it was enough to add a filter with the criterion "Contact is in my adress book" and run it.

This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
