Error in HypergeometricPFQ-package?

The following HypergeometricPFQ-function generated by the
SymbolicSum-Package gives an error when I try to derivate it. I use
Mathematica 2.2 and I have followed the Hypergeometric Fix (Technical
Note) I found on MathSource.

D[HypergeometricPFQ[{1/2,1,1},{2,2},4.77206 hit1],hit1]

Thread::tdlen: 
   Objects of unequal length in 4.77206 <<1>> + {0, 0} + {0, 0, 0}
     cannot be combined.

Has anybody a solution for this problem?

Helge
