Public bug reported:

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
[5] wxEntry(int&, wchar_t**)
[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.)
