Sorry for the delayed response here.  I've been away from the computer
this weekend and somehow overlooked the bug coming in last week.  But I
am now aware of it and will look into it.

Do you know whether the problem occurred after the most recent security
update?  There was a security fix to some of the code that affects G4.
I will take a closer look and see whether a recent update may be
responsible for this problem.  I'll try to get something up as soon as I
can to fix it, but updating the stable release is slow.  Let's see if
maybe this is a regression caused by the security fix in squeeze2.  I'll
try to get to this within the next day or two, but any assistance in the
investigation would be gratefully appreciated.  For example, if you
could determine whether the problem affects 3.9.4-5+squeeze1 or the
versions in wheezy and sid.  You could temporarily install the wheezy or
sid libtiff4 packages on squeeze; there are no incompatible changes in
the dependencies at this point.  You could then go back to the squeeze
version after testing.  If you don't have time or inclination, no
problem.  I will test as soon as I can.
