I can confirm that with the following diff empathy works without no
problem on a last-week up-to-date sid on libvirt/KVM with no HW
acceleration:

Until this week-end Mesa updates (see below), it seemed that there was
another way: installing libgl1-mesa-swx11 solved the problem for two
up-to-date sid, a schroot and the libvirt/KVM above. However, in the
latter case GNOME 3 always crashes and I can not login (this should be
confirmed on a real machine, i.e. not on a VM). So the situation was
the following:
1) libgl1-mesa-glx alone
=> empathy segfault
2) libgl1-mesa-glx *AND* libgl1-mesa-dri *AND* HW acceleration
=> empathy works
3) libgl1-mesa-swx11 (with or without libgl1-mesa-dri)
=> empathy works, but GNOME 3 crashes
libclutter-1.0 already Depends: on 'libgl1-mesa-glx | libgl1' and this
includes also libgl1-mesa-swx11 (which Provides: libgl1). What it could
be needed is a Depends: on 'libgl1-mesa-dri | libgl1-mesa-swx11':

It seems that upstream Mesa already solved this in a different way:
<https://bugs.archlinux.org/task/26686>
<https://bugzilla.redhat.com/show_bug.cgi?id=747276#c18>
The upstream fix went into the new Mesa package during the week-end (I
was building the old 7.11-6 plus this patch, but given that the build
process needed more than 5 GB of disk space I could not get it earlier):
<http://anonscm.debian.org/gitweb/?p=pkg-xorg/lib/mesa.git;a=commitdiff;h=b2fbf8225bfed2d6f5339ba0a97ddbc5e6cc491a>
<http://packages.qa.debian.org/m/mesa/news/20111128T002111Z.html>
Nevertheless, empathy still segfaults witwh libgl1-mesa-glx_7.11.1-1
alone (i.e. without libgl1-mesa-dri) on both sid above, the schroot and
the libvirt/KVM. However, the error on the latter is a bit more
explicative:
=====
luca.capello@gismo-sid:~$ empathy
(empathy:2824): Clutter-CRITICAL **: Unable to initialize Clutter: \
The OpenGL version could not be determined
Segmentation fault
luca.capello@gismo-sid:~$ empathy
=====
Installing libgl1-mesa-dri solves the problem, which is anyway a
progress, given that before it did not work at all on libvirt/KVM with
no HW acceleration (see point 2 above).
Thx, bye,
