I have the same problem with k3b on 64bit Hardy:
k3b: symbol lookup error: /usr/lib/libk3b.so.3: undefined symbol: stat64
Howto reproduce: Initially I had to start k3b, select VideoDVD project and try to add files to reproduce the crash.
Right now it crashes immediately after start.
Noticed this today, worked fine one month ago (I believe I used it later as well, but I'm not 100% sure)
