[web2py] SQLFORM grid

[peter]

I am having the following problem when I use 'edit' on SQLFORM grid, and 
then submit the changes. I tried downloading the latest trunk and also 
created the app afresh to ensure things were otherwise clean

ERROR SNAPSHOT [image: help]

<type 'exceptions.ValueError'>(unsupported format character 'D' (0x44) at 
index 45)

the view the 'edit' is diverting from is

def view(): iconup = IMG(_src=URL('static','images',args='up.png') ) 
icondown = IMG(_src=URL('static','images',args='down.png') ) 
table=SQLFORM.grid(db.labels,deletable=False,create=False,csv=False,details=False,
 
orderby='label',paginate=300) return dict(table=table)

Thanks
