Segmentation fault on ImageToBlob if compression failed

Segmentation fault on ImageToBlob if compression failed.
Yes, it is also a bug in JasPer, that cannot compress such image, but it is not reason to Segmentation fault.
If i use WriteImage instead of ImageToBlob, i got just get false as result.
Image for test: http://img.gt2.ru/idx-83.bmp
ImageMagick version: 6.5.0-2
Operation system: openSUSE 11.1
Some problem also appeared on CentOS 5.2 with ImageMagick 6.4.9-4
