Some time ago I ran into probably the same issue; how to load an
array/table at load time, while said array/table is not guaranteed to
have loaded yet. From within an object there is nothing like a loadbang
AFAIK. I ended up setting a timer for one second (clock_new()) and load
the array/timer when it finishes.
But the good news is that just preventing partconv~ to crash shouldn't
be too difficult.

Still it is a good idea to make detailed bug reports. Fixing issues is
much simpler if you know exactly what the problem is.
