Thanks. Committed a slightly modified version.

We are using spaces for indentation, no tabs. (There are some place
where tabs are still used. But I try to keep at spaces.)

Title:
  assert "IsOpened()" failed in GetFirst() when running in debug mode

Status in Hugin - Panorama Tools GUI:
  Fix Committed

Bug description:
  When compiling in debug mode and running from the build directory, an
  assertion is triggered due to the missing plugins directory.

  ASSERT INFO:
  ./src/unix/dir.cpp(275): assert "IsOpened()" failed in GetFirst(): must wxDir::Open() first

  BACKTRACE:
  [1] wxDir::GetFirst(wxString*, wxString const&, int) const
  [2] MainFrame::MainFrame(wxWindow*, HuginBase::Panorama&) /home/sean/pkg/hugin-hg/src/hugin/src/hugin1/hugin/MainFrame.cpp:371
  [3] huginApp::OnInit() /home/sean/pkg/hugin-hg/src/hugin/src/hugin1/hugin/huginApp.cpp:315
  [4] wxAppConsoleBase::CallOnInit() /usr/include/wx-3.0/wx/app.h:93

  [6] main /home/sean/pkg/hugin-hg/src/hugin/src/hugin1/hugin/huginApp.cpp:118
  [7] __libc_start_main
  [8] _start

  The attached patch fixes the issue by checking whether the dir open
  succeeded before attempting to access it. (I used hg diff this time,
  let me know if it's formatted right.)
