Strange bug in ListPath<>

Description (last modified by )
Valgrind report an error on the following code:
ListPath<ListDigraph> p,q;
p.addBack(a);
q=p;
The problem seems to be that q=p tries to copy bitwise instead of using the template ListPath<>::operator=() implementation.
Implementing a non-template version solves the problem, but I don't understand why the template version is used.
I fear that this issue may affect other Path structures, or even other tools, too.

The issue has been fixed in [7440937d154b] and merged to all relevant branches (1.1,1.2,default).
The reason for the problem is the usual utmost stupidity of C++ - the default copy constructor is of higher priority than an explicitly defined template one.
