Umm. Err. What? If the startup used to get you into the infinite recursion
(that's what happens in the "return path("bimaps/empty.png");"...)

Oh, never mind. I bet your libssrfmarble isn't compiled with debugging
enabled, so the qDebug never gets printed for you.

Can you replace the qDebug with

fprintf(stderr, "fullpath %s results in %s\n", qPrintable(fullpath), qPrintable(result));

(completely untested, typos and thinkos included free of charge... but
something along those lines should work...)
