I had written a vmd-molfile-plugin for reading my trajectory files.
Generally, it is working fine. But now it crashed, because the pointer
'ts->coord' that was given to the 'read_next_timestep(...)'-function is
zero. This happens at a 'random' time step, i e. for one input file, it
happens on the same time step, but for another input file the time step

Even if I handle this case within the function, VMD crashes after the

I wonder now, if the pointer 'ts->coord' is allowed to be zero, if 'ts'
is non zero. Can it be that my plugin is responsible for this behaviour?

Many thanks,
