While the reason for for the rooms map missing the weight should be
investigated, here is a patch that makes the code assume the exit has no
extra weight on it, instead of causing a crash. This is much better
behavior.

Title:
  Crash on pathfinding

Status in Mudlet the MUD client:
  New

Bug description:
  Crashed on pathfinding with:

  0	TMap::initGraph	TMap.cpp	970	0x5da0ef	
  1	TMap::findPath	TMap.cpp	985	0x5da2d8	
  2	TMap::gotoRoom	TMap.cpp	767	0x5d84e2	

  The code in question gets the room weight of a special exit:

          if( rooms[i]->other.size() > 0 )
          {
              QMapIterator<int, QString> it( rooms[i]->other );
              while( it.hasNext() )
              {
                  it.next();
                  int _id = it.key();
                  if( ! rooms[i]->hasSpecialExitLock( _id, it.value() ) )
                  {
                      edgeCount++;
                      edge_descriptor e;
                      bool inserted;
                      tie(e, inserted) = add_edge( i,
                                                   _id,
                                                   g );
                      weightmap[e] = rooms[_id]->weight;
                  }
              }
          }
