kis_image_magick_converter compile error

[Michael Thaler]

Hello,

Right now, Krita does not compile for me:

kis_image_magick_converter.cc: In member function `KisImageBuilder_Result
   KisImageMagickConverter::buildFile(const KURL&, KSharedPtr<KisLayer>)':
kis_image_magick_converter.cc:541: error: `alpha' undeclared (first use this
   function)
kis_image_magick_converter.cc:541: error: (Each undeclared identifier is
   reported only once for each function it appears in.)
kis_image_magick_converter.cc: In member function `KisImageBuilder_Result
   KisImageMagickConverter::buildFile(const KURL&, KSharedPtr<KisLayer>,
   KSharedPtr<KisAnnotation>*, KSharedPtr<KisAnnotation>*)':
kis_image_magick_converter.cc:661: error: `alpha' undeclared (first use this
   function)
make: *** [kis_image_magick_converter.lo] Error 1

Does someone has the same problem? Can someone fix that?

Greetings,
Michael
