Hi.  I'm currently running Fedora 7 with these packages:

amarok.i386                              1.4.6-2.fc7            installed
amarok-extras-nonfree.i386              1.4.4-1.lvn7          installed
libmusicbrainz.i386                      2.1.4-1.fc7            installed
libtunepimp.i386                        0.5.3-3.fc7            installed
libtunepimp-extras-nonfree.i386          0.5.3-1.lvn7          installed

I mostly listen to mp3 files.  I've noticed that if a musicbrainz tag lookup returns no matches (or maybe some other failure), subsequent lookups will just go forever, chewing up CPU.  I have to restart amarok to get it working again.  I saw a bunch of related bug reports, but many were old and marked as resolved.  Do others see this problem?

Thanks, reid

Following up....  I have seen it work for me now after a zero-match lookup, so maybe it was actually failing some other way before.  It still sometimes gets into a state where it hangs on further lookups, eating CPU, but now I'm not so sure what's doing it.  Wish I could provide more details....
