Identifying JPEGs give wrong results

Hi,
we use ImageMagick for identifying image metadata like size, resolution etc. in a database publishing system (by using identify -verbose). We have noticed that since some versions, IM gives the wrong resolution for jpegs saved by Photoshop CS2 (result is always 72 ppi). Photoshop, TheGimp or IrfanView give the correct resolution, so I presume that it is IM's fault.
Here are some examples:

The correct resolution is indicated in the image's title.
Thanks for having a look (and, if possible, a quick solution...)
