Discussed at 2015-01-12 blocker review meeting: http://meetbot.fedoraproject.org/fedora-blocker-review/2015-01-12/f22-blocker-review.2015-01-12-16.06.log.txt . Accepted as a Final blocker per criterion cited.

Still valid today. Any news?

I'm making an educated guess this is caused by the tracker issue - https://bugzilla.redhat.com/show_bug.cgi?id=1192197 - based on the strace: the last file accessed aside from translations is /usr/share/gnome-documents/js/trackerController.js and one of the last things that happens is it connects to a dbus socket and winds up getting a 'Resource temporarily unavailable':

connect(7, {sa_family=AF_LOCAL, sun_path=@"/tmp/dbus-VsWIdU5JHm"}, 23) = 0
fcntl(7, F_GETFL)                       = 0x2 (flags O_RDWR)
fcntl(7, F_SETFL, O_RDWR|O_NONBLOCK)    = 0
geteuid()                               = 1001
getsockname(7, {sa_family=AF_LOCAL, NULL}, [2]) = 0
poll([{fd=7, events=POLLOUT}], 1, 0)    = 1 ([{fd=7, revents=POLLOUT}])
sendto(7, "\0", 1, MSG_NOSIGNAL, NULL, 0) = 1
sendto(7, "AUTH EXTERNAL 31303031\r\n", 24, MSG_NOSIGNAL, NULL, 0) = 24
poll([{fd=7, events=POLLIN}], 1, 4294967295) = 1 ([{fd=7, revents=POLLIN}])
read(7, "OK 2c0b3f28ad4aab84df04b4ca54dbc"..., 2048) = 37
poll([{fd=7, events=POLLOUT}], 1, 4294967295) = 1 ([{fd=7, revents=POLLOUT}])

read(7, "AGREE_UNIX_FD\r\n", 2048)      = 15
poll([{fd=7, events=POLLOUT}], 1, 4294967295) = 1 ([{fd=7, revents=POLLOUT}])

poll([{fd=7, events=POLLIN}], 1, 25000) = 1 ([{fd=7, revents=POLLIN}])
recvmsg(7, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\n\0\0\0\1\0\0\0=\0\0\0\6\1s\0\5\0\0\0:1.92\0\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 260
recvmsg(7, 0x7fff538742f0, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable)

so, yeah, I'm guessing it's the same thing.

I was seeing this too, but today it magically just started working.

Can you still reproduce ?

Still broken here (and I have the gnome-documents from two days ago). There hasn't been a tracker build for a while.

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.

More information and reason for this action is here:

Seems to be working here now too, on my desktop and in a clean VM.
