Comment:

 Ok as requested, ive install valgrind and ran as below, there was a minute
 or so delay while it moved past 29352 but then halted on the sytax error
 so i control+c'd it which then generated the rest - is this more useful to
 you.  At no point did pidgin display at all, is this just how valgrind
 works?
