[Replicant] cloning of https://git.replicant.us/replicant/frameworks_base.git permanently fails due to "error: RPC failed; curl 56 GnuTLS recv error (-9): A TLS packet with unexpected length was received."

[Karl-Philipp Richter]

Hi,
The last days, I'm having trouble with cloning
https://git.replicant.us/replicant/frameworks_base.git both manually and
through `repo sync`. I get

    > git clone https://git.replicant.us/replicant/frameworks_base.git
    Cloning into 'frameworks_base'...
    remote: Counting objects: 739930, done.
    remote: Compressing objects: 100% (196567/196567), done.
    error: RPC failed; curl 56 GnuTLS recv error (-9): A TLS packet with
unexpected length was received.
    fatal: The remote end hung up unexpectedly
    fatal: early EOF
    fatal: index-pack failed

100 % of > 10 tries within 24h. According to
https://bugs.launchpad.net/ubuntu/+source/gnutls26/+bug/1111882 this
occurs as a temporary issue and might indicate an error in the web
server configuration.
