Package: mtd-utils
Version: 20090217-1
Severity: normal
running mkfs.jffs2 causes a segfault when you use the -v parameter if
files in the directory are owned by a user.
I generated this report via reportbug on the system in question, and
sent it via my normal mail client, since reportbug didn't like my MTA.
---------------------------------------------------------------------
Steps to reproduce..
# mkdir foo
# touch foo/bar
# chown jean.jean foo/bar
# ls -Flan foo/
total 8

After compiling from package source, a backtrace from gdb results in...
# gdb --args /home/jean/mtd-utils-20090217/mkfs.jffs2 -v -r foo -o
