It most certainly will... This bug is exceedingly annoying every time one 
tries to do some work with anything vaguely related to integration of 
anything even remotely apparented to hypergeometric functions an/or using 
the binomial formula. Thankyouthankyouthankyou...

I'd like to suggest an "expedited release" for this one.

BTW : The main Maxima page (http://maxima.sourceforge.net/, which is the 
firs occurence found by google) points to 5.28.0 as "the last release" ; 
the Sourceforge files page points to 5.29.1 as the latest. The Source and 
Linux subpages both have 5.31.0, Windows and MacOSX both have 5.30. A it 
of cleaning up might be beneficial here...

Thanks a lot again !
