While I've filed a bug against empathy (that is where I observed the
problem), I suspect other packages are impacted and the issue may need
to be fixed at some other level.

Empathy itself does not required GL libraries to be installed:

However, Empathy depends on Clutter which itself requires an OpenGL
implementation:

Checking the depends of libclutter-1.0-0:
glaubitz@znote-t60o:~$ apt-cache depends libclutter-1.0-0 |head
libclutter-1.0-0
Depends: libatk1.0-0
Depends: libc6
Depends: libcairo-gobject2
Depends: libcairo2
Depends: libcogl-pango0
Depends: libcogl9
Depends: libfontconfig1
Depends: libfreetype6
Depends: libgdk-pixbuf2.0-0
glaubitz@znote-t60o:~$
where you see a dependency on libcogl9 which in turn depends on MESA:
glaubitz@znote-t60o:~$ apt-cache depends libcogl9 |head
libcogl9
Depends: libc6
Depends: libgdk-pixbuf2.0-0
Depends: libglib2.0-0
Depends: libx11-6
Depends: libxcomposite1
Depends: libxdamage1
Depends: libxext6
Depends: libxfixes3
Depends: libgl1-mesa-glx
glaubitz@znote-t60o:~$
So, whatever you do, don't mess around with Empathy. The bug, if any, is
not in Empathy but any of its dependencies. I'd have a look at Clutter.
Also, have you tried running Empathy on a non-compositing window manager
when libgl1-mesa-dri is not installed?
Cheers,
Adrian
