listed-incremental bug

[Milos Prudek]

I seem to have found a bug in GNU tar 1.13.25.

--listed-incremental fails to backup only changed files. Instead it 
backs up 90% of full backup, although literally no file have changed.

Subsequent incremental backup cuts down the percentage to 40%, and only 
the 4th or 5th incremental backup ends with empty archive.

I am still trying to pinpoint the cause. It seems to be related to the 
size of backup (around 1 GB), number of files (34622 files), or the fact 
that the backup spans three filesystem types (ext2, ReiserFS, FAT32).

Is there a limitation in tar, such as number of files for 
--listed-incremental?

My command line is: tar --create --absolute-names --gzip 
--listed-incremental=SNAPSHOT --files-from=LIST --exclude-from=EXCEPT 
--file full.tar.gz
