I'm afraid I got the same bug... sadly for me I lost the file and I have to create an empty tags.xml with two lines, and lose all the color tags and subtags... :(. After that, I recovered all my tasks with their respective tag, but as I was saying - no color nor sub-tags.
I don't know what happened, I think it was a X crash, but I don't know hot to debug it (the only thing I know that it was today).
It wouldn't be a bad idea to backup the file the same way the xml for the tasks is backed up.
