Title:
  assistant fails to run if custom temporary directory is set

Status in Hugin:
  Fix Released

Bug description:
  If preferences->file name->Temporary dir is set to an non-empty value,
  running from cpfind from the Assistant ([2. Align]-button]) fails. The
  cpfind window pops up and closes immediately, an error message about
  unconnected images is shown.

  Running cpfind from the main window ([Photos]->[Create control
  points]) still works.

  Googling finds a thread on hugin-ptx but no solution:

  | For the record: setting that variable (which ends up in ~/.hugin as
  | tmpDir=/var/tmp, for example) appears to cause hugin pass an empty
  | PATH environment variable to icpfind, which then fails.  It's not the
  | problem of icpfind, which works fine if started directly.  But I
  | haven't had time to track it down yet.
