ReiserFS doesn't like GlusterFS?

ReiserFS comes as a default filesystem on my Slackware box and somehow I notice that ReiserFS does not seem to like GlusterFS. The system locks up while doing xattr operations and dmesg reports bunch of warnings before locking up:

[ 229.328509] REISERFS warning (device sda6): jdm-20001 reiserfs_xattr_get: Invalid magic for xattr (trusted.gfid) associated with [10723 11732 0x0 SD]

This happened twice, I am not sure if it is a co-incidence, however I will try to reproduce it more definitively before concluding. This takes a very low priority for two reasons:

a. GlusterFS is not recommended with ReiserFS
b. ReiserFS itself is no longer being developed or supported.

I have used ReiserFS as backend for GlusterFS before and this didn't seem to happen. Or maybe the usage pattern was different, I'm not sure.
