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
