Exception merging grayscale Tiff

[Foto99]

Good afternoon

I have tested 1.3.13 Lite version and found it great. I tried an upgrade to 1.4.13 but it hangs when processing grayscale tiff 16 bits images (which were processed OK with the 1.3.13 version) altough it works OK with RGB images. Images are medium format negative scans 2400 bpi.
System windows vista 64 bits

Should I downgrade back to 1.3.13 or do you think there is a solution? thanks by advance

This error occurs on all files?

Tested on about 5 grayscale tiff files that I could tonemap with version 1.3.13

I can not get this error. You can share me the source files?

Here is the link (i did a low-res exemple, which gives the same problem than the high-res ones)
