<pre>Ok, that's a little unexpected. Do you mind compiling with --enable-debug=full
and attaching the compressed logfile?
I think
diff --git a/src/sna/sna_dri2.c b/src/sna/sna_dri2.c
index b2814da..2750497 100644
--- a/src/sna/sna_dri2.c
+++ b/src/sna/sna_dri2.c
@@ -1203,6 +1203,10 @@ __sna_dri2_copy_region(struct sna *sna, DrawablePtr
draw, RegionPtr region,
assert(region == NULL || region == &clip);

}
dst_bo = dst_priv->bo;
will prevent the crash, but we shouldn't be reaching that point.</pre>
