Tanu, again: Thanks for your help.
I tried the patch and various other changes to log.c, but getting no
useful logging, and sometimes segfaults instead (as you also noted).
My mind kept coming back to this:
ldd /bin/gnome-shell | grep pulse
libpulse-mainloop-glib.so.0 => //lib/libpulse-mainloop-glib.so.0
(0xb5771000)
libpulse.so.0 => //lib/libpulse.so.0 (0xb5723000)
libpulsecommon-2.1.so => //lib/pulseaudio/libpulsecommon-2.1.so
(0xb56b7000)
libpulsecommon-2.99.so => //lib/pulseaudio/libpulsecommon-2.99.so
(0xb4da6000)
So, I deleted every file installed by the original pulseaudio 2.1,
recompiled+installed pulseaudio 2.99.2, and recompiled+installed
gnome-shell.
Now I have:
ldd /bin/gnome-shell | grep pulse
libpulse-mainloop-glib.so.0 => //lib/libpulse-mainloop-glib.so.0
(0xb56e3000)
libpulse.so.0 => //lib/libpulse.so.0 (0xb5695000)
libpulsecommon-2.99.so => //lib/pulseaudio/libpulsecommon-2.99.so
(0xb5620000)
(A quick look at gnome-shell source did not reveal why it would link to
an old version; I must have a closer look at this later).
And the good news:
Now the clients (incl gnome-shell) are showing the "Received opcode" in
~/.xsession-errors (presumably because they log to stderr which is
redirected to ~/.xsession-errors).
And the even better news:
I have tried to recreate the freeze without success.
So, maybe 2.99.2 solved the original problem after all.
However, I am still having some trouble...
Syslog show as lot (about 5/sec to 10/sec) entries like:
Nov 26 16:31:04 kx8400-5 pulseaudio[2078]: (1745.440| 0.057)
[pulseaudio] pdispatch.c: [0x9ee32f0] Received opcode
<GET_PLAYBACK_LATENCY>, tag 1088
And ~/.xsession-errors shows the corresponding
Received opcode <REPLY>
I am not sure if this is a problem or not, but previously I did not
notice such pulseaudio bursts in syslog.
Further thunderbird crashes every now and then (maybe not related, but
it never did that before),
and sometimes the terminal does not beep as expected.
For the latter case (terminal does not beep as expected) I have this in
syslog:
