In current Fedora Rawhide / 22, it seems that various bugs trace back to not being able to communicate with tracker via dbus, and the underlying cause of that appears to be this: [adamw@adam wikitcms (master %)]$ /usr/libexec/tracker-store (tracker-store:5401): Tracker-CRITICAL **: Fatal error dealing with ontology changes: NOT NULL constraint failed: nfo:Media_nfo:hasMediaStream.nfo:hasMediaStream (strerror of errno (not necessarily related): No such file or directory) (tracker-store:5401): Tracker-CRITICAL **: Cannot initialize database: NOT NULL constraint failed: nfo:Media_nfo:hasMediaStream.nfo:hasMediaStream (strerror of errno (not necessarily related): No such file or directory) [adamw@adam wikitcms (master %)]$ I'll have the other bugs depend on this one.
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle. Changing version to '23'. (As we did not run this process for some time, it could affect also pre-Fedora 23 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
Fixed upstream in 1.3.4, which got into F22.
