When you run "pdebuild --help", it's equivalent to running the first
the command specified after the #! on the first line followed by the
path to the script and arguments you gave, in this case

 /bin/bash /usr/bin/pdebuild --help

By running

 bash -x /usr/bin/pdebuild --help

you're basically running the same command, except you're also passing
-x which causes the shell to print out each command as it executes it.

Hmm, this looks the same as the trace on my system, except that it
prints out the help information just before calling exit.  Do you have
the standard output redirected somewhere weird?
