Does it crash if you assign the tag by selecting all images and adding the tag from the "Comments/tags" tab of the right sidebar?
Does it crash if you drag-and-drop the other way, dragging all selected pictures on the tag in the left or right sidebar?

No it does not crash in these situations. Only if I drag the tag one photo and 
then say "assign tag to all photos". 

However I found out one more thing. By default I have activated the option to 
store tags in the photos IPTC metadata. If I turn this option of in digikams 
setup then the crash does no longer happen.

Try to fix crash

Still not reproducible here...I have three ideas:

- recompile with --enable-debug, run digikam under gdb and provide a backtrace
(instructions in HACKING file)
- try if the attached patch fixes the problem
- in your debug log, there are the lines

digikam: WARNING: No album found for ID: 4915295 // take the ID shown here

This is probably the problem! Please check then if there is such an image in
your database:
 sqlite3 <your library path>/digikam3.db "SELECT Albums.url, Images.name FROM
Images JOIN Albums ON Images.dirid = Albums.id WHERE Images.id=<ID from debug
log>;

Ok, I did. Here are the last lines up to the crash:

This message happened only one time I do not see it any longer. But the crash 
still happens each and every time I assign a tag to all the photos. So this 
is probably not the reason.


Rainer

Sorry in my report yesterday I forgot the  backtrace :-( . Well I tried again 
and this time (on another host with not 100% the same photos) and I did a 
backtrace. By the this time there are again the messages "No album found for 
ID: 7471215". But using the SQL-statement you gave to me a query for an id 
like the one above results in an empty string.

Rainer

Thanks for your debugging.
It still seems that the ImageInfos list the method operates on is invalid, I dont think you have 7 million images ;-)
This would explain the crash, it happens when a member variable of the invalid object is accessed.
I don't know when and where the relevant object are deleted. I will commit the patch anyway because now that the UI is not locked while tags are applied, I can imagine situations where this list becomes invalid. But I cannot proof that the patch solves the problem.

Pass a copy of current ImageInfo list to changeTagOnImageInfos
