TortoiseIDiff - problem with multipage TIFF files

I've discovered that TortoiseIDiff doesn't work correctly with multipage TIFF files.
When I try to compare multipage TIFFs, the first pages of two compared files are displayed OK.

The problem comes when I push either "Previous", "Next" or "Animate" buttons above any of compared images.

The program crashes with unhandled Win32 exception and displays Windows message
"TortoiseIDiff has stopped working"
A problem caused the program to stopped working correctly. Windows will close the program and notify you if a solution is available".

Technical details:
OS: Vista Business 32-bit, SP2;
TortoiseSVN: 1.6.6, 32-bit;

How to reproduce:
To create multipage TIFFs I've downloaded bunch of arbitrary PDF files from the Internet. Then I've converted PDF files to TIFF using Ghostscript (latest version - 8.70) with the following command:

"C:\Program Files\gs\gs8.70\bin\gswin32c.exe" -dNOPAUSE -sDEVICE=tiff24nc -dBATCH -sOutputFile=test.tif test.pdf

Then just started TortoiseIDiff:

TortoiseIdiff /left:test.tif /right:test.tif

and clicked on the above mentioned buttons.

Just in case, I've tried to use various -sDEVICE parameters (such as tiffg4, tifflzw, ... etc.) with no luck.

Also (just to make sure that GhostScript is not the source of the problem) I've tried to convert source PDF to TIFF with IrfanView 4.25 as well. That didn't help either.

Any ideas?
Thanks for your attention.
