Hi Soizic,

Thank you for sharing the problematic images (lovely cat by the way :))).

I think I know what's causing issues with PM, the metadata of the file is corrupted (not badly, but I think badly enough for PM to choke on it). As part of this, the caption looks really weird:
Code: [Select]
Canon PowerShot S90
objectif :

6mm f/5 1/10" ISO1000

Focus:   WB:
Mtring:? `MMOD_unknown’

Comp:  0.0ev  +989.2

sRGB IEC61966-2.1 (embedded)
fichier : 1.4MB  JPEG
crop : 1800x1350 (1.33)
Print: 15.3 x 11.4 cms, 300 pixels/inch
Ê
V¿∑ö‰éák û W}÷ _Fb∑n¿ÜG2∞
W

If I check the file with exiftool -a -validate -warning I get a fair number of warnings:
Code: [Select]
Validate                        : 15 Warnings (all minor)
Warning                         : [minor] Possibly incorrect maker notes offsets (fix by -142978?)

Warning                         : [minor] Unknown IFD0 tag 0x9219

@Kirk, does this help tracking down the cause of the hang?

That's a pity, so some software has corrupted them (or, also possible, you ran into an issue called bit-rot where – over time – 0s and 1s change) :(
The good news is though that the image data itself seemed to be intact. It's just that PM can't currently handle slightly corrupted metadata.

You're not the only one by the way, I took Frederic's example image from his post and I could definitely reproduce the scan to catalog to hang with that. I'm sure this will help CameraBits to fix the issue.
