Description Piotr 2015-05-31 09:33:35 UTC 
I have setup digikam to save tags to files also. So when tagging (lest say 50 files at once in one go) sometimes but too often digikam dies. The debugging info is pasted below (I hope usefull, I was using built in kde critical bug manager).

Also I'm able to hang (looks like infinite loop) digikam when I put into its queue more than one tagging session. What I mean is: select some pics, tag (digikam works) than select another ones and tag them (digikam put them into the queue) than select another one and so on. After a while digikam just does nothing (no crash, simply looks like nothing happens). This state is in the picture attached.


Reproducible: Sometimes

screen shot of digikam progress bar

The writing means: 'Saving metadata to files'
Comment 3 Piotr 2015-05-31 10:05:58 UTC 
So the bug is outside digikam. What can I do to make digikam usable 'now'? 

PS
The debug info I have sent was usefull? How have you  discovered the origin of the bug ;-)?
Comment 4 caulier.gilles 2015-05-31 10:07:29 UTC 
It crash in Qt Sqlite database plugin, especially in SQlite code...

You must update sqlite3 AND Qt4 Sqlite plugin...

Gilles Caulier
Comment 5 Piotr 2015-05-31 10:22:46 UTC 
Well, I'm on LTS Kubuntu and rely on their packages. SQLlite is not updated there. Not good.
Are package maintainers of the sqlite3 and qt4 plugin aware of the problem?
Comment 6 caulier.gilles 2015-05-31 10:41:54 UTC 
Ho, i just seen this in the GDB backtrace :

#16 0x00007f2fe03b562c in Baloo::FileModifyJob::doStart (this=0x7f2f5c014fc0) at ../../../../src/file/lib/filemodifyjob.cpp:113

In fact, it's not the digiKam Database which is broken, but the Baloo DB. Go to setup/Metadata/Baloo dialog page and disable Baloo support. This must fix your problem.

I forward this file to Baloo...

Gilles Caulier
Comment 7 Piotr 2015-05-31 11:17:18 UTC 
Baloo...
https://bugs.kde.org/show_bug.cgi?id=348417

Baloo is to young to work reliably I'm afraid.
Comment 8 Piotr 2015-05-31 12:18:00 UTC 
I can confirm that the problem after disabling baloo has gone. And I was on heavy tagging task ;-)
Sorry baloo...
Comment 9 Vishesh Handa 2015-06-02 13:47:43 UTC 
Fixed with Baloo KF5.
