Everything is fine again! I can mount the filesystem again. Solution for
my issue and to the issue above was, that the wrong cipher was used. 

I did an upgrade of debian/sid and got updates for the kernel 2.6.32 and
for cryptsetup to version 1.1.0. Probably the default cipher did change
without notice. After a power loss and reboot this problem occured, but
it was not the power loss itself.
