This is a very bad thing to do but I think what happens is that spanning tree will block fa 0/16 for both vlans. You have a loop and it has to block someplace. Since it is blocking the connection between the vlans the pc can't talk. If you would move the root to the layer 2 switch it may block one of the trunks and it may work. Not that I recommend you do that.
Actually, if the two ports were in different vlans, they would both be forwarding. One would be a root port and the other a designated port. My guess is that the ports that you connected together are actually trunking, which means that you did not connect vlan 2 to vlan 5 but vlan 2 to vlan 2 and vlan 5 to vlan 5 on the same box;-)
How I'm guessing that? Because one port is backup (which means that it is blocked receiving bpdus from the same bridge). And also because the default priority for a bridge running extended sysid is 32768 + vlan #. So I can see that vlan 2 has a root ID with a priority of 32770 and vlan 5 priority 32773.
If you configure your port as access, you will merge vlan 2 and vlan 5 and vlan 2's root will become vlan 5's root (because 32770 < 32773).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
