There was a bug in the Elgamal signing key code in GPG back then.   
There is no longer a bug... and there is also no longer Elgamal  
signing key code.  Elgamal signing keys were dropped from the OpenPGP  
standard in RFC-4880, and so will not be supported in GPG.



As a side note, are there any other possible algorithms that may be
used to generate a signing key other than DSA/RSA/ElGamal.


Yes, but not in OpenPGP.
