[Pkg-utopia-maintainers] Bug#639647: dbus-x11: dbus-launch causes ssh -Y user at host to hang after logout

[Francesco]

Package: dbus-x11
Version: 1.6.8-1
Followup-For: Bug #639647

Dear Maintainer,

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I made a connection and started a program. I expected "only" dbus-launch process, but there are some 
kdeinit4 processes. In ssh connection (whith -v) I can see more than one channel opened:

debug1: client_input_channel_open: ctype x11 rchan 3 win 65536 max 16384
debug1: client_request_x11: request from 127.0.0.1 53094
debug1: channel 1: new [x11]
debug1: confirm x11
debug1: client_input_channel_open: ctype x11 rchan 4 win 65536 max 16384
debug1: client_request_x11: request from 127.0.0.1 53095
debug1: channel 2: new [x11]
debug1: confirm x11
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.debug1: client_input_channel_open: ctype x11 rchan 5 win 65536 max 16384
debug1: client_request_x11: request from 127.0.0.1 53096
debug1: channel 3: new [x11]
debug1: confirm x11

debug1: client_input_channel_open: ctype x11 rchan 6 win 65536 max 16384
debug1: client_request_x11: request from 127.0.0.1 53097
debug1: channel 4: new [x11]
debug1: confirm x11
debug1: channel 3: FORCE input drain

[...]
debug1: channel 6: new [x11]
debug1: confirm x11
debug1: channel 3: FORCE input drain
debug1: channel 3: free: x11, nchannels 8
debug1: channel 6: FORCE input drain
debug1: channel 6: free: x11, nchannels 7

Killing stuck dbus and kdeinit4 processes unlocked the situatione and correctli returned
to source shell:

logout
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
debug1: client_input_channel_req: channel 0 rtype eow at openssh.com reply 0
debug1: channel 0: free: client-session, nchannels 7

debug1: channel 1: FORCE input drain
debug1: channel 2: FORCE input drain
debug1: channel 1: free: x11, nchannels 6
debug1: channel 2: free: x11, nchannels 5

debug1: channel 9: FORCE input drain
debug1: channel 9: free: x11, nchannels 4


debug1: channel 5: FORCE input drain
debug1: channel 5: free: x11, nchannels 3
debug1: channel 3: FORCE input drain
debug1: channel 3: free: x11, nchannels 2
debug1: channel 7: FORCE input drain
debug1: channel 7: free: x11, nchannels 1

For further info I launched a qt program, but gtk software seems affected too (gvim as stated from Russel); simple
x11 programs seems not affected (e.g. xclock). Maybe the bug is related to desktop base or library
complexity
