[Bug-tar] tar segfaults with using --listed-incremental

[Curt Blank]

openSuSE 11.3
Kernel 2.6.34.7-0.5-default
tar 1.23
Filesystem ext4

Starting with you guys.

When I run

tar -vv -cRf test.tar --listed-incremental=root.db --one-file-system -b
256 --totals / > test.log

and root.db does not exist tar completes successfully. If root.db exists
from a previous run tar segfaults and I see this in messages:

Nov  2 03:34:48 router kernel: [21938.384366] tar[29989]: segfault at 0
ip 000000000042e390 sp 00007fffc30ad078 error 4 in tar[400000+58000]

This is 100% repeatable whether I output to a file or a SCSI tape drive,
delete root.db it runs fine, if root.db exists from a previous run it
segfaults.

If I backup /opt or any other ext4 filesystem thus mount point I do not
have this problem, seems to only occur when attempting to do an
incremental backup of .(root). This just started occurring with openSuSE
11.3 install done two days ago.
