[Shotwell] error making latest git with Vala 0.15.1 on Fedora 16

[Eric L]

I'm running Fedora 16 x86_64 with Vala 0.15.1 installed
This is the last lines of the output of make from the latest git pull:

Compiling Vala code...src/photos/PhotoMetadata.vala:131.13-131.75: error: Return: Cannot convert from `uchar?[]' to `uint8[]'            return owner.exiv2.get_preview_image(props[number]).get_data();            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^Compilation failed: 1 error(s), 0 warning(s)make: *** [src/.stamp] Error 1

Should I file a bug?
