I also habe this problem, but it happened while I'm changing some Filenames in my music collection after I've changed about 10 Filenames the collection scanner closed.
I am Using Ubuntu Edgy Eft and I've got a Music Collection of about 170GiB. ** Attachment added: "Crash Dump of broken collectionscanner" http://librarian.launchpad.net/5423425/_usr_lib_amarok_amarokcollectionscanner.1000.crash -- amarokcollectionscanner closed unexpectedly https://launchpad.net/bugs/61188 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
