sure. thx for the 'analysis'. but wrong choir ;-)

@ desktop,

  install ubuntu + 1pass, all good
  install debian + 1pass, all good
 install redhat + 1pass, problems -> fixed by changing ptrace_scope default to = 1  install fedora + 1pass, problems -> fixed by changing ptrace_scope default to = 1

Why though? It doesn't make any sense that a program only works
when ptrace is more restricted unless it's deliberately checking
that setting and refusing to run when it is zero.

Setting it to 1 might be fine for an average user but for anybody
using their machine for development work it will be a real problem.
