K3b/mkisofs fails with Joliet directory tree should start at 286 but starts at 283.

[Gioele Barabucci]

K3b is unable to write some Mixed CD projects. I keep getting the following error:

    mkisofs
    -----------------------
    19733
    Warning: creating filesystem that does not conform to ISO-9660.
    === last message repeated 2 times. ===
    /usr/bin/genisoimage: Warning: -C specified without -M: old session data will not be merged.
    19733
    Warning: creating filesystem that does not conform to ISO-9660.
    I: -input-charset not specified, using utf-8 (detected in locale settings)
    /usr/bin/genisoimage: Warning: -C specified without -M: old session data will not be merged.
    /usr/bin/genisoimage: Implementation botch: Joliet directory tree should start at 286 but starts at 283.

The error appears when the data track is about to be written. The audio track is written fine. I can reproduce this error (I produced various faulty CDs trying to understand what the problem was).

I tried performing a simulation before burning the CD and the simulation completes without any problem.
