** Description changed:
I'm experiencing this problem with Ubuntu Saucy. Some times, when I start a
media player (I use Musique), it freezes, as it finds that it cannot write into
/run/user/$ID/pulse.
If I change the owner of that directory to me, the media player starts as
usual and is able to play music.
I've never had this problem with previous versions of Ubuntu.
Someone says that running PulseAudio with the -D argument changes the owner
of that directory, but I didn't try.
This is before manually changing the owner of that directory:
$ musique
Failed to create secure directory (/run/user/1000/pulse): Permission denied+
... # it doesn't crash, it keeps waiting

This is a fresh installation, I haven't updated it from a previous version.
I'm using Ubuntu with Unity, not a derivative.

- SRU TEST CASE:
+ SRU INFORMATION
+ ===============
+ TEST CASE:
- Ensure that as a normal user "echo $XDG_RUNTIME_DIR" is something like
"/run/user/1000"
- do "sudo su -" to get a root shell
- - In that root shell, do "echo $XDG_RUNTIME_DIR". In the saucy final package
this still gives /run/user/1000, which is incorrect for root and leads to
destroying the real user's runtime dir. With the fixed package it should be
empty.
+ - In that root shell, do "echo $XDG_RUNTIME_DIR". In the saucy final package
this still gives /run/user/1000, which is incorrect for root and leads to
destroying the real
+ user's runtime dir. With the fixed package it should be empty.
+
+ Fix: http://bazaar.launchpad.net/~ubuntu-
+ branches/ubuntu/trusty/systemd/trusty/revision/58 : This checks if the
+ runtime dir delivered by logind (which is based on the session uid) is
+ owned by the target user, and only puts it in the environment if it is.
+
+ Regression potential: The only case where a runtime dir from a different
+ user could work at all is for opening a su/pkexec session as root; but
+ any client using the runtime dir (pulseaudio, dconf, etc.) would destroy
+ the original user's runtime dir, and we don't have any functionality
+ which depends on this. For non-root su/pkexec targets this potentially
+ leads to different errors (inaccessible $XDG_RUNTIME_DIR vs. a
+ nonexisting one). But again the practical impact is limited to things
+ that you do in su/pkexec shells, not in "real" desktop/ssh/VT login
+ sessions.
