Title:
  compiling PTBatcherGUI: invalid conversion from ‘const wxChar*’ to
  ‘wxChar*’

Status in Hugin - Panorama Tools GUI:
  Fix Released

Bug description:
  There's a minor problem in PTBatcherGUI on my system (Kubuntu 11.4,
  using wxWidgets 2.8) when compiling bleeding edge hugin
  (5216:b7b7c4cbbfd0), python_scripting branch. Here's what the compiler
  says:

  [ 80%] Building CXX object src/hugin1/ptbatcher/CMakeFiles/PTBatcherGUI.dir/PTBatcherGUI.cpp.o

  I'm sure it's just an oversight somewhere, but the virtual wxWidgets
  function that's overridden actually returns a wxChar*, and the
  overriding function tries to return wxEmptyString, which seems to be
  of const wxChar* type. I used a temporary workaround here and cast
  wxEmptyString to (wxChar*), but this should be fixed properly.
