I'm seeing a regression with:
commit 79f11b35c77b3c286c84312dc9737c2ccbf67ed5
Author: Eric Blake <eblake@xxxxxxxxxx>
Date: Tue Apr 8 14:26:02 2014 -0600
conf: track user vs. canonical name through full chain lookup

Format specific information:

Before the patch:
$ sudo virsh vol-dumpxml /mnt/data/devel/images/f18.qcow2
[full xml with backing image info]
After the patch:
$ sudo virsh vol-dumpxml /mnt/data/devel/images/f18.qcow2
[xml minus xml for the backing image]
And these errors are on the console when the daemon starts:
2014-05-03 20:52:34.970+0000: 20600: error : virFindBackingFile:590 : Cannot
access backing file './f18-backing-img.qcow2': No such file or directory
2014-05-03 20:52:34.970+0000: 20600: warning :
virStorageFileGetMetadataInternal:868 : Backing file 'f18-backing-img.qcow2'
of image '/mnt/data/devel/images/ztester-serial-f18.qcow2' is missing.
On git head actually the vol-dumpxml explicitly fails, but I don't have the
error handy.
