I have a stack of 4 Cisco Switch 3750 (1 x WS-C3750G-24T, 2 x WS-C3750-48P and 1 x WS-C3750V2-48PS) and I want to do an firmware upgrade of this stack. Actually, all the 4 switches are at the firmware version 12.2(50) SE1 "IPBase" and I want to upgrade them to 12.2(55)SE5 IPBase.
According to the release notes, all the switches in my stack are supported.
from your image looks like its trying to download the image twice. can u please try again and once its copied. check the flash if the new image is already there. if yes, then ignore the message because the switch was trying to download the image twice perhaps...
What happens if I delete the "old" bin file on the each of the 4 switch and upload then the new bin file to them?
Is there any risk with this action? It is the main backbone switch!
I would be very careful with things like this especially in production devices..will wait to see if any others have any ideas as why the switch is behaving liek that. if you get no help here then raise a TAC case to find out why its doing this.

When moving from OSPFv2 to OSPFv3, there are many changes in the format of the LSAs Type, but the most known changes are: IP prefix informations are no longer carried in Type-1 LSA and Type-2 LSA, new LSAs Type 8 and 9 are added to carry these prefixes.
