Fix bug in IsoFileSrc implementation, related to a wrogn usage of tsearch.

Browse Source 
It happens that tsearch seems to not return a pointer to the inserted element,
but a pointer to a pointer to the inserted element (that makes sense, as we
are inserted pointers...). This bug, thus, was related to a wrong 
understanding of the tsearch API!
