[poppler] Bogus memory allocation size

[suzuki toshiya]

# This is an interim report.

Now I'm testing the latest trunk, at:

	commit 753f6ab9347f972223ec21b7ed4b4f7ebed3d420
	Author: Albert Astals Cid <aacid at kde.org>
	Date:   Thu May 3 15:29:57 2012 -0700

	    Compile with ENABLE_PLUGINS defined

And the stracktrace when "Bogus memory allocation size" is
raised is following. objSize=567193 would be scaledHeight,
nObjs=16101 would be 3 times of scaledWidth=5367.

Yet I'm not sure what to do when the scaled image is too
huge to hold in single buffer.
