Right, found what I suspect is a bug in the python bindings for 0.26

The script calls

sg = findfile(rec.basename, rec.storagegroup, db=db)

But in the source I find:

def findfile(filename, sgroup, db=None):
    """
    findfile(filename, sgroup, db=None) -> StorageGroup object

    Will search through all matching storage groups, searching for file.
    Returns matching storage group upon success.
    """
    db = DBCache(db)
    for sg in db.getStorageGroup(groupname=sgroup):
        # search given group
        if sg.local:
            if os.access(sg.dirname+filename, os.F_OK):
                return sg
 
Now, thanks to some debugging I find

sg.dirname+filename == /var/lib/mythtv/recordings1029_20121023230500.mpg

So, change the call to

sg = findfile('/'+rec.basename, rec.storagegroup, db=db)

and the script runs. (Haven't yet checked whether it has found the breaks correctly)

Looks like sg.dirname is stripping a trailing slash where it shouldn't. Where should I report this?
