Doing a copy/paste inside a gtktextview under Win32 will sometimes fail to
paste the text properly.

This is due to a logic error in gdk/win32/gdkselection-win32.c, function
_gdk_selection_property_store:

prop->length = strlen (prop->data + 1);

instead of

prop->length = strlen (prop->data) + 1;

I love C...
