My guess is that by the time that destructor is executed, the runtime 
has been shut down sufficiently that the ~ operator cannot work. The 
following has the same error:

import std.stdio;

string foo()
{
     return "abc";
}

class Foo
{
     ~this() {writeln(foo() ~ "xyz");}
}

void main()
{
     new Foo;
}
