Description Blackpaw 2013-05-31 14:33:34 UTC
When email indexing is enabled nepomuk storage crashes after 10-20 seconds. It then restarts and eventually crashes again. Rinse and repeat ...

If I disable email indexing nothing crashes.

Reproducible: Always

Steps to Reproduce:
1. Stop neopmuk
2. Stop akonadi
3. Ensure Email indexing is enabled
4. Start nepomuk (from console)
5. Start Akonadi
Actual Results:  
The feeder will start indexing, eventually round the 50% mark the nepomuk storage service will crash (reported on the console). The storage service will restart as will the indexing and the problem repeats.

Expected Results:  
Indexing should complete. Nothing should crash.

akonadiconsole often hangs using 100% of a core when using it to restart or abort the feeder.

Disabling the feeder leaves the kmail and kde feeling much more responsive - I hadn't realised how much it was impacting thing.

Also I was having problems with read items becoming unread, this has stopped since I disabled the feeder. I thought it was a sync problem but maybe it was due to the storage service continually crashing.

I've done a clean and rebuild of nepomuk, akonadi, kdepim-runtime and kdepim from master.

Where is the backtrace ?
Comment 2 Blackpaw 2013-06-01 11:56:52 UTC
- Sorry, never received an email notification that a comment had been added.


Not getting an apport report. Just see a report on the console that nepomukstorage has crash once, restartting, twice etc. The PID changes in the task list.

I tried running nepomukstorage under gdb using kdevelop and got this:

*** Program received signal SIGPIPE (Broken pipe) ***
*** Error in `/home/lindsay/Projects/akonadi/nepomuk-core/build/services/storage/nepomukstorage': munmap_chunk(): invalid pointer: 0x00007fffdc00c100 ***

This is what I'm seeing on the console after a "nepomukctl start"

And this is what I see on a separate console after a "akonadictl start", around the time of the storage crashes

Comment 5 Vishesh Handa 2013-08-17 11:39:35 UTC
This seems like it is a problem with some strange strings in the email -

Eg - <http://www.semanticdesktop.org/ontologies/2007/08/15/nao#prefLabel> "???????????????@softlog.com.au\r"

The strings should probably be properly sanitized in Nepomuk. Could you please forward me this email? The Akonadi item id is 63298
Comment 6 Vishesh Handa 2015-03-17 12:39:06 UTC
The Nepomuk project is no longer maintained in KDE since 4.13. For email indexing, Baloo provided an Akonadi resource to index emails, contacts and events. Tags are now maintained by Akonadi itself.
