Description Wyatt Childers 2015-09-29 22:07:24 UTC 
Application: plasmashell (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Occasionally when I search using the Application Launcher Plasma Shell crashes. I've noticed this primarily when I quickly hit the backspace key after rapidly entering text into the search box.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

liblmdb issue mdb_txn_begin(MDB_env *env, MDB_txn *parent, unsigned int flags, MDB_txn **ret) does not check parameter MDB_env *env is NULL!

and in void mdb_txn_abort(MDB_txn *txn), it also forget to check txn->mt_env

We have worked around it for 5.17. We really should have had more error checking on our part. I'm leaving this open for now. I want to see if we still get any crashes as it was not easily reproducible.

In that case I'll attach my backtrace from after upgrade to kde-frameworks-5.17 (I think it's related).

Please also note that I have baloo file search disabled.
Comment 16 Vishesh Handa 2015-12-15 11:35:15 UTC 
@Andreas: Could you possible send me your Baloo database?

It should be present at ~/.local/share/baloo/index. This would really help be diagnose what is going wrong.

Hi Vishesh:

Sorry. I don't longer have OpenSuse Tumbleweed + KDE installed because of
stability issues. I changed to Leap + KDE and everything is working fine.

Thanks a lot.

Btw you should have received it some time ago, unless it ended up in your spam filter.

@Michael could you get me the output of 
$ balooctl checkDb
and it would also be helpful if you could upload your baloo database (~/.local/share/baloo/index)
so that I can try looking at what's wrong.

$ balooctl checkDb
Baloo Index could not be opened

I have baloo disabled and unfortunately recently deleted the database to see if it would help with the crashes (it seems to).

A corrupted/incomplete database could indeed be the cause - if I recall correctly, I did have to manually kill baloo_file_extractor in the past.

Can you try moving the baloo database somewhere safe (please keep it as it could be useful for debugging if the issue is resolved) and restarting plasma to see if the crashes stop?
Comment 29 Tom Chiverton 2016-08-11 19:17:47 UTC 
The only thing that worked was balooctl disable; balooctl enable and now balooctl status reports
Baloo File Indexer is running
Indexer state: Idle
Indexed 15624 / 118006 files
Current size of index is 74.84 MiB
Comment 30 Tom Chiverton 2016-08-15 19:39:46 UTC 
Given the well defined exception, and recovery steps, why doesn't Baloo do disable /enable automatically when it occurs? 
Overhead of a rescan less bad than no indexing

I "fixed" that baloo_file now detects if the db can't be opened and recreates it, therefore the baloo_file crashs here are solved, but yeah, I am not sure if the Query handles corrupted databases very well :/

Use other bug for query problem if db is corrupt.
