    bliptv: Fix crash when browsing on 64-bit platforms
    
    gsize on 64-bit platforms is a 64-bit integer. Trying to fit a 64-bit
    integer in the 32-bit integer we were passed trashed the pointer of the
    previous return parameter, in this case the buffer's address.
    
    Pass a pointer to correctly sized integer to avoid this memory
    corruption and cast it later as needed.
