sample pdf which triggers the described error

When rasterizing a PDF containing certain cyrillic characters ghostscript reports an error. This problem seems to be related to DejaVu Sans fonts, since the problem does not occur when using different fonts

The two characters are Ё (U+0401) and ё (U+0451). If a PDF is generated containing the character Ё ghostscript reports the following error:

GPL Ghostscript 8.63: Unrecoverable error, exit code 1
convert: Postscript delegate failed `test_1025.pdf': No such file or directory.
convert: missing an image filename `test.png'.


The PDF was generated with xelatex, but the same error occurs if the PDF is generated with Open Office Writer and exported as PDF. The problem does not occur if another font (e.g. FreeSerif) is used.


Steps to reproduce:
 * use attached PDF test_1025.pdf
 * run: convert test_1025.pdf test.png

Software used: 

 * up to date Ubuntu 8.10
 * ttf-dejavu package version 2.25-1
 * convert: ImageMagick 6.3.7 08/21/08
 * GPL Ghostscript 8.63
