I updated Krita to the latest build: 2+git20130828+r74350-40-dk~raring1 Since this build it it's impossible to create or assign new Tags. Creating a new tag and afterwards assign a ressource to the tag does not work (the tag isn't shown). Right click on a ressource and then create a tag works but isn't saved and is gone with the next start. Reproducible: Always Kubuntu 13.04 (Raring) Kernel 3.8.0-30 KDE 4.10.5
I have investigated this problem again and now the tags are working again. That's what i did... I checked if it's still not working - not working - okay.. I remembered that i had disabled Autosaving. Although i am sure that this setting shouldn't influence the saving of tags to the xml files in any way, i reenabled the setting and tagged a ressource and surprisingly - it was saved again. Restarted krita again, unchecked autosave - tagging still works. So this is solved for me - strange thing, but I think it was a temporary problem, that will never happen again, and never could be explained logically^^
ok :-)
