JFFS2: bug in mkfs.jffs2 recursive_populate_directory

[Arno Steffen]

I found another bug in mkfs.jffs2 (in recent 1.4.2) version.
Generate a jffs2 file with -v (Verbose) option ends up with a
segmentation fault, caused by the prints.
I am not 100% sure, but it seems to be connected with another bug I
reported alredy. In my case, the segfault dissapear, if owner of root
( -r /opt/rootfs_build/opt/configs) is switched from user to root.
