Any images I've edited using Picasa and saved to disk are no longer parsable by ImageMagick:
You can find the .orig/20081025T181312.jpg referred to in the code above at this URL:

Can someone confirm whether this is an ImageMagick bug or whether the JPEG image data is actually corrupt (a Picasa bug)?
I know the image renders just fine in any image viewer I can throw it at.

By the way, this is ImageMagick 6.4.8-1 (MacPorts) and 6.4.8.3 (Gentoo).
Picasa v3.0.2 (OS X)

The JPEG delegate library issues the exception, not ImageMagick. It should be a warning meaning the conversion completes.

The conversion does complete generating a pure black image of the correct dimensions.

The conversion was successful for us. We're using ImageMagick 6.4.8-9 under Fedora Linux.

Same issue with 6.4.8-9 here.
More specifically:
6.4.8-9 +graphviz +gs +hdri +jbig +jpeg2k +lcms +lqr +mpeg -X +perl +q16 +rsvg +wmf (MacPorts)
6.4.8-3 +graphviz -gs -hdri -jbig +jpeg +jpeg2k -lcms -X +perl -q32 -q8 -svg -wmf (Gentoo)

This is using jpeg 6b_3

I suppose I can try building without jpeg2k.

It seems likely the problem is in the version of the JPEG library you use. Its always best not to trust images with corrupt data. It leads to unpredictable results as you are seeing here.
