Title:
  traceback is suppressed when deploy.loadapp fails

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  I saw this error when attempt to start a relatively recent quantum (setup.py --version says "2013.2.a782.ga36f237"):
       ERROR: Unable to load quantum from configuration file /etc/quantum/api-paste.ini.

  After running quantum-server through strace I determined that the
  error was due to missing mysql client libraries:

      ...
      open("/lib64/tls/libmysqlclient.so.18", O_RDONLY) = -1 ENOENT (No such file or directory)
      open("/lib64/libmysqlclient.so.18", O_RDONLY) = -1 ENOENT (No such file or directory)
      open("/usr/lib64/tls/libmysqlclient.so.18", O_RDONLY) = -1 ENOENT (No such file or directory)
      open("/usr/lib64/libmysqlclient.so.18", O_RDONLY) = -1 ENOENT (No such file or directory)
      munmap(0x7ffcd8132000, 34794)           = 0
      munmap(0x7ffccd147000, 2153456)         = 0
      close(4)                                = 0
      close(3)                                = 0
      write(2, "ERROR: Unable to load quantum fr"..., 95ERROR: Unable to load quantum from configuration file /usr/local/csi/etc/quantum/api-paste.ini.) = 95
      write(2, "\n", 1 )                       = 1
      rt_sigaction(SIGINT, {SIG_DFL, [], SA_RESTORER, 0x3eec80f500}, {0x3eef90db70, [], SA_RESTORER, 0x3eec80f500}, 8) = 0
      exit_group(1)

  
  The error message is completely bogus and the lack of traceback made it difficult to debug.

  This is a regression from commit 6869821 which was to fix related bug
