Exporting that, I instead get:

Program received signal SIGILL, Illegal instruction.

If I add the signal handling instruction to GDB suggested above, I
instead get:

libvisual WARNING: no progname: visual_plugin_get_list(): Failed to add the /usr/lib/libvisual/transform directory to the plugin registry
** (rhythmbox:21196): WARNING **: Could not initalize the HAL context: (null)
** (rhythmbox:21196): WARNING **: Could not initalize the HAL context: (null)

...which makes Rhythmbox work again.   

Analyzing this, the crash is consistent with the only significant change
between 0.10.1 and 0.10.3, which is the addition of the visual plug-in.

Creating the missing /usr/lib/libvisual/transform directory does not fix
the bug, however. Rhythmbox still fails to start normally (without GDB).

As another test, starting Rhythmbox from an xterm where the OILCPU_FLAG
above is exported, indeed works.

So I guess this narrows down the problem to something liboil-related.
