Bug#335615: Confirmed & patch.

[Daniel Burrows <dburrows@debian.org>]

  I just wrote a simple test program (attached) and it indeed exhibits
an infinite recursion.  The attached patch fixes it (in my test case,
it gets replaced by a crash because the queue is empty, but obviously
that's expected :) ).

#include <apt-pkg/acquire.h>

int main(int argc, char **argv)
{
  pkgAcquire aq;
  pkgAcquire::Queue q("Foo", &aq);
  pkgAcquire::UriIterator uit(&q);
  ++uit;

  return 0;
}
