Are you sure you copied the right files, the ARM ones?

If you copied the symlink, did you also copy the actual file?

The /etc/ld.so.conf file on your ARM board tells the dynamic linker where to 
search for libraries.

What we need is the libdbus-1.so.3 file somewhere where the dynamic linker finds 
it.

Make sure that QtDBus can find and load the libdbus-1 library.
