Rygel 0.24 as shipped in Fedora 21 has a bug that causes it to continue to list deleted files. This was fixed in upstream commit 081631721ce206cdb704e7b6f2c01ac6de555e3a. Please upgrade the Fedora 21 Rygel package to 0.26 when it is released or (preferably) cherry pick the fix into Fedora's 0.24 package.
Fedora 21 will stay on 0.24.x, I'll review the patches when I get a spare moment, or hopfully upstream will release a bugfix .x release
