Beagled plays with xattr, and /home is mounted is mounted with the following options:
/dev/mapper/vglinux1-lvhome /home reiserfs rw,noatime,nodiratime,user_xattr 0 0

This happens on one user account only. But this is 100% reproducible. (I guess xattr on this account are somewhat corrupted).


Steps to reproduce:
- mount /home with user_xattr
- run beagled
