I am getting a repeatable error with the following message:

Gasman: has no handle for a bag of type [1] and size     20.

What I would like to know is if any one recognises this error and knows
of a probable cause. I suspect that the problem is with my own code as I
am dealing with recursively nested lists at this point in the
calculation, but smaller examples work fine so I am confused by the
error. If anyone has any thoughts then I would be pleased to hear them.

This error message tells you that GAP run out of memory. More precisely
GAP was just trying to allocate memory for a list (type '[1]') for 5
elements ((<20 bytes> - <4 bytes for the length>) / <4 bytes per element>).

This is of course also the reason why you don't see this happen when you
try the smaller examples.

I suggest that you start GAP with the '-g' option to see how large GAP
gets before it finally gives up (GAP extends its workspace until the
operating system refuses to give GAP any more memory).
