Summary: unable to read file's content for a file on NTFS system

Initial Comment:
This issue is specific to NTFS file system only.
TSK’s routine “tsk_fs_file_read” returns an error while trying to read content of a file (for "Bitmap Image.bmp"  ) by some specific offset.
Reading is done as a sequential reading from beginning to an end of a stream.
Error message is “tsk_fs_read: Offset is too large for image: 2043904”.
Error goes from a point where routine tries to read raw data from a “$Data” attribute – reading from data runs.
Seems like error is at the routine where offset is calculated for NTFS for some particular data run.
I tried the same set of files but on Ext3 and Fat32 file systems: no errors – content reading was done successfully.
I supplied mentioned partitions to a posix-sample application (from a TSK‘s package) – the same result: reading data from a file fails always on NTFS, but succeeded for Ext3 and Fat32.

Message:
That error means that it is trying to read past the end of the file system.
Can you do the following:
- provide the size of the disk image
- Use 'icat' to extract the file contents (icat -o OFFSET_OF_FILESYSTEM
IMAGE_NAME INODE)
