Problem with imread/rtifc after upgrade to 2012b

I have been using a function written in 2010 with no problems until today when I upgraded to 2012b (I had previously been using 2011b with no problems). I'm trying to read in a multi-page tiff using imread and get the following error:

Error using rtifc
TIFF library error: 'TIFFReadDirectory: Incorrect count for "ColorMap"; tag ignored.'.

Error in readtif (line 49)
[X, map, details] = rtifc(args);

Error in imread (line 434)
    [X, map] = feval(fmt_s.read, filename, extraArgs{:});

I'm not an expert on the tif file format so any help trying to diagnose the problem or with a work around would be greatly appreciated. Thanks.

Installed 2012b two days ago, exactly the same error. The TIF file is fine, can be opened with other imaging software.

Same problem with me.

Please send the TIF file to Technical Support so they can determine if there
is a problem with the TIF reading functionality or if the file has been
written incorrectly or using a feature that is incompatible with the TIF
standard that prevents MATLAB from opening it but is compensated for by the
other software.

I installed the work around files and it solved my problem. Thanks.

I have the exactly the same problem with you. Do not have any idea...

After installing the patch, it can work now. But it comes with a warning:

Warning: TIFF library error: '_TIFFVSetField:
C:\Users\GH\Desktop\standard_test_images\cameraman.tif: Null count for "Tag 34022" (type 1,
writecount -3, passcount 1).'. The image data may be corrupt.

i have the same problem using Matlab 2013a 64Bit on Linux. i tried to apply the workaround for 2012b but failed causing the following error:

Invalid MEX-file
'/usr/local/MATLAB/R2013a/toolbox/matlab/imagesci/private/rtifc.mexa64':
/usr/local/MATLAB/R2013a/toolbox/matlab/imagesci/private/rtifc.mexa64:
undefined symbol:
_ZN6MATLAB8imagesci5rtifc16noImageSpecifiedC1Ev

Is there a workaround for 2013a?
