Bug Description

exaile 0.3.1.1
vlc 1.0.6

panflute launches the players, but is unable to detect and communicate with them. dbus-send calls simply queue up. When killed, the music player processes become zombies for quite some time before panflute-daemon collects them.

I've run panflute-daemon in debug mode for exaile:

On an unrelated note, shouldn't the mpd connecter time out after a while?

Also:

$ ps aux | egrep -i "panflute|exaile" | grep -v "egrep -i panflute|exaile"
... python /usr/bin/panflute-daemon -d
$ ps aux | egrep -i "panflute|exaile" | grep -v "egrep -i panflute|exaile"
... python /usr/bin/panflute-daemon -d
... dbus-send --session --print-reply --type=method_call --dest=org.mpris.panflute /Player org.freedesktop.MediaPlayer Pause
... python /usr/lib/exaile/exaile.py --datadir=/usr/share/exaile/data --startgui
later (many seconds, but before the dbus-send command times-out) ...
$ ps aux | egrep -i "panflute|exaile" | grep -v "egrep -i panflute|exaile"
... python /usr/bin/panflute-daemon -d
... dbus-send --session --print-reply --type=method_call --dest=org.mpris.panflute /Player org.freedesktop.MediaPlayer Pause
... python /usr/lib/exaile/exaile.py --datadir=/usr/share/exaile/data --startgui
later (some more dbus-send commands) ...
$ ps aux | egrep -i "panflute|exaile" | grep -v "egrep -i panflute|exaile"

One a brighter note, MOC and Quodlibet have several python warnings, but work nonetheless:

unfortunately, I couldn't test rhythmbox because it's import music process kept freezing up.

the MOC error is especially annoying:
can't unmount network music shares
can't switch panflute control to another player

I can confirm this issue too. moc interface is completely broken...when I close mocp (with mocp -x to kill the server), it keeps respawning .... because of panflute...
Besides, I think there should be a way to enable/disable which players are active (just like it was before, when panflute was called music applet).

Can you check if the problem persists with Panflute from the bzr repo? I've made some changes in the course of chasing down other bugs that could possibly have fixed this one too.

A player not appearing in the list means its support module failed to load. The only obvious cause for that would be if you don't have python-notify (or whichever package in your distro provides the pyinotify module for Python).
