and two fanart items failed to cache entirely - Alien and Spider-man 3.

Spider-man 3 is actually very unusual. It is a jpeg encoded with CMYK colourspace (jpegs are generally YUV).

jpegsnoop reports:
"NOTE: Scan parsing doesn't support CMYK files yet."

QuickTime displays it with incorrect colours. I think that is just a weird file and you'd be best to convert it or download a different version.

====edit====

Also xbmc's slow jpeg decoder reports:

Code:

16:26:04 T:2922026048 WARNING: JpegIO: Error 28: Unsupported color conversion request

so it's not entirely happy.

However, the file is useful, as we weren't quitting out as early as possible.
I've now made the first sign of "bitstream corrupt" quit out, and I parse the number of colour components to reject CMYK before sending data to GPU.

Alien is working every time for me (when decoded on its own).
I imagine the current timeouts only occur in complex scenarios (mutliple concurrent jpegs being encoded/decoded).
If you have a repeatable failure I'd be interested.
