Does Android have issues with 1024-bit certificates?

I have run into an issue where Android (versions 3.1 and 2.3.4) throws a:

javax.net.ssl.SSLPeerUnverifiedException: No peer certificate 

error accessing an RSS server that has a Versign V3 1024-bit certificate (CN = VeriSign Class 3 Secure Server CA - G2). I can access a different server using a Versign V3 2048-bit certificate and it is fine. Does anyone know if Android has issues with the older 1024-bit certficates?

The actual stacktrace looks like this:

You should have a look at this thread :

1024-bit SSL certificates provider

It looks like it's just too weak to use 1024 bits ssl certificates. I looked at the code from apache harmony but the API seems to be a bit complex (and clumsy to be honest as some fields are modified outside the SSLImpl class), and I couldn't find much more information.

It looks like the best solution would be to ask for a modern 2048 bits x509 certificate form your web hosting provider.
