TIFF split problem

[sniz]

I have a perl script that splits multi-page tiff files using IM convert, and every once in a while, I'll run into a tiff containing an orientation tag with a bad value*. IM does separate the page from the original tiff, but gives a return code of '1'
Is this proper behavior? I'd expect a warning in this case. The resulting tiffs are usable, but I can't rely on checking the return code now to see if the split succeeded.

the convert command i'm using is: convert -define quantum:polarity=min-is-white -compress Group4 -quiet 0511.tif[0] 0511_front.tif

* identify gives me this:
0511.TIF[0] TIFF 1200x554 1200x554+0+0 1-bit Bilevel DirectClass 16.5KB 0.000u 0:00.000
0511.TIF[1] TIFF 1200x558 1200x558+0+0 1-bit Bilevel DirectClass 16.5KB 0.000u 0:00.016
identify: incorrect count for field "Orientation" (2, expecting 1); tag trimmed. `0511.TIF' @ warning/tiff.c/TIFFWarnings/704.
