Here is a simple version of the code:
restart;
plots[textplot]([4,2,q[n]]);
plotsetup(gif,plotoutput=`p.gif`);
plots[textplot]([4,2,q[n]]);
plotsetup(default);
This hangs Maple. (Maple 15.01 running on Mac OS 10.6.8.) Maple 12 is OK, but Maple 13 is bad, so that must have been where some change came in. Omit the subscript, no problem. Replace gif with jpeg or ps, problem remains.
