[GAP Forum] AbsoluteIrreducibleModules error

Dear Forum,

According to the Manual, the command AbsoluteIrreducibleModules(G, F, dim)
returns a list of all absolutely irreducible modules of G over the
field F in dimension dim.
However, it seems to produce an error if the field F is not prime.

C:=CyclicGroup(3);
AbsoluteIrreducibleModules(C,GF(4),1);

Error, List Element: <list>[1] must have an assigned value in
...

Certainly, the modules in this example are easy to find by hand, but I
first came about
this error when trying to compute a more complicated and meaningful example.

Thank you,
Anvita
