I would have guessed that you will get some memory problem when running with "--backend Files" or one of the Evolution backends. Since that didnot happen, some other backend is causing the problem. As you pointed out, there are a 2 other backends that have some data. Can you also test those 2 ?
$ beagled --backend KonquerorHistory .... and $ beagled --backend none --add-static-backend /var/cache/beagle/indexes/applications --add-static-backend /var/cache/beagle/indexes/documentation -- beagled uses >250 Megs RAM when Idle https://launchpad.net/bugs/87198 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
