Lightroom: White Vignette in corners of HDR image

Every time I try to create HDR photo from vertical photos I get white vignette around corners in finished photo. From horizontal photos I don't have any issues. The problem only occurs when using portrait raw files with Photo Merge> HDR and the  tamron 70-200 A009E Canon profile. If I switch to any other Tamron profile, for example tamron 70-200 A009N, the issue is gone.

The Canon version of the profile file is missing a critical piece of information that trips up the HDR DNGs but not the CR2s. 

Specifically, the Canon profile doesn't have an stCamera:SensorFormatFactor="1" attribute on each rdf:Description tag which seems to be needed, because if I edit the profile and add this attribute then the profile doesn't show white vignetting:

It's unclear if the other two tags are needed or not.  The profile isn't automatically detected, probably due to the lack of a LensID attribute, but perhaps Tamron on Canon cannot use this.

Here is a list of all lens profile files as of ACR 9.5.1 & LR 6/2015.5.1 that have no stCamera:SensorFormatFactor attribute on the rdf:Description tag.  I have emboldened the one profile we're discussing, here, but the rest may also have the same vignetting problem in an HDR DNG:

c:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0>grep -d -i -c "SensorFormatFactor" *.lcp > \sff.txt
c:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0>grep ":0" \sff.txt

The first two lines show the greps that were done to first count then filter for count-of-zero.  I have removed the :0 count from the end of each filename in the list before posting, here.

Thanks, Steve! I have confirmed that this fixes the bug. 

We'll have it fixed in a future release.
