That's not very special for reiserfs.
On non-journaling file-systems you can only pray the file data and the
meta-data are in sync. fsck will find most of it, but you can still have a
problem like this if you're unlucky.
And all journaling file systems that write the meta data before the actual
file data have this problem, which means pretty much all of them. IIRC only
ext3 can be configured to write metadata after the write, which is slower but
more safe. ext3 can even be told to write the file data (!) to the journal,
causing 100% correct replays of transactions. Needless to see that's terribly
slow, and ext3 already was slower for partitions with lots of small files
than reiserfs...
In general it's a tradeoff between performance and 100% data security whether
to pick reiser or ext3. For most applications reiser is already far more
reliable than any non-journaling system out there.
