I think there are two bugs at work here and both are out of the scope of 
the nvidia driver.

1. Signing the kernel module fails. That's probably your local 
configuration that activates it, or do we have packages adding support 
for that now? I've never looked into signing the kernel module.

Can you send me your signing bits (and instructions how to generate a 
key) s.t. I can try to rebuild that setup in a chroot in order to 
reproduce the bug?

2. dkms getting some hickup after the package configuration failed (due 
to the signing failure) and not properly reinitializing on the next 
attempt. (The relevant maintainer script bits should all come from dh_dkms.)
