Thank you for the sample image, it does allow to reproduce the crash. The crash seems to be caused by some misconfiguration inside the metadata of that TIFF file. It is likely that it is originally caused by the software that wrote that TIFF. Perhaps it is related to the thumbnail embedded into this TIFF.
We will investigate it in more details to prevent such crashes on corrupted TIFFs.
In the meantime, a possible solution would be to re-save the corrupted TIFF into another file format (PNG does work and it is also lossless like TIFF) and then import it into Aperture instead of that TIFF. Neat Image will then be able to work without crashing, I have tested that.
I will let you know when we find out more about the issue.
Thanks for the prompt answer! converting to PNG sounds like a feasible workaround. I did not expected malformed TIFF file, as Aperture manages to read it...
The thing is, Aperture does read it not entirely correctly and then sends an incorrect information to the plug-in, that causes the issue. When you convert it to PNG, Aperture reads it properly and plug-in also receives the right image.
