A couple of weeks back, I had to rename ~/.kde and ~/.local to fix a whole bunch of issues that had been building up for a long time. Can’t remember specifically what they were by now, but it was necessary.
When I was running Kubuntu Karmic, I tagged a bunch of images. I’m currently on Kubuntu Lucid. None of my images are tagged. I wonder if the upgrade killed the tags. The tags are still recognized (if I go to tag an image, the old tags are still listed), but no images are tagged. I guess I’ll continue to not tag files.
It’s just as well. Some other images I hadn’t tagged yet, I mass-renamed them from the command line, and that would have wiped out the tags if they had any.
