I'll start with the crash log.
File is 120MB tiff from Library of Congress Archives online ar160300. You can download the MrSID viewer and export the image as a TIFF. Trying to save as a jpeg. Crash happens before preview is drawn in Save Dialogue. Also uses 100% of both cores for a long time and TONS of memory before the crash. I'd look at the code myself as .NET is what I do, but time isn't in my favor for doing that right now.

[EDIT] - Additionally, the processor is an X2-4200. Just in case it's related to the physical hardware. I know that I've had a couple of problems with apps reading the timestamp counters on dual core AMD's (eg. Mozilla Thunderbird) correctly.
[EDIT2] - Crash is actually on jpeg quality change. Seems to produce an error no matter which way I go with the slider, but if I go from default to 100% I usually get the crash. If I go from higher quality to lower, then the "File Size: " label under the preview changes its status to error. The images below are task manager related to PDN. My host seems to be down right now (blizzard and all), but I'll check back to make sure they work once it's back up.
