Question
As diskimages-helper is prominent, should I treat this as a bug in Apple software?
Observations
The only image used at the time of the panic was stored on ZEVO (Community Edition 1.1.1). One of two LaCie enclosures on the FireWire 800 bus of a MacBookPro5,2 with 8 GB memory. A sparse bundle disk image used by Time Machine. At the time of the panic, backupd was probably removing expired backups.
The pool/dataset involved is currently known as flakylaciebde and is known to be imperfect, but not so much that I'd expect a panic. copies=2
http://www.wuala.com/grahamperrin/publi ... de=gallery includes a few things from before the panic.
http://www.wuala.com/grahamperrin/publi ... de=gallery includes screenshots and other information gathered soon after the panic. As far as possible, I connected and mounted things as they were before the panic.
