Comment 54 for bug 123460

Same problem here as Voltaire with Ubuntu 10.04 and Rhythmbox 0.12.8.

It seemed frozen for a while, but after a long delay it allowed me to close the error message window and then after another long delay another one appeared (again frozen for a while and then let me close the window and so on). After about 20 minutes it finished the process and I unmarked the "Watch my library for new files" option in the preferences. I logged out, and restarted rhythmbox. This time was really frozen. I erased the file ~/.local/share/rhythmbox/rhythmdb.xml as suggested by Voltaire and restarted the program. Added all my libraries again and closed. Logged out and logged in and restarted rhythmbox. I seems to be working fine now (but of course it won't look for new songs).
