This looks like it could be a bug, so maybe you should submit a
complete bug report to the address@hidden list?  It would help a lot
if you included enough information so that someone could reproduce the
problem.  Send a precise recipe for triggering the bug (the exact
sequence of commands you used) and include all the data needed (the
image that fails).  More tips on bug reporting can be found here:
