Git pull problems on Yggdrasil

Hi,

Recently when pulling on Yggdrasil from bitbucket.org-based repository I often get the following error:

HEAD is now at XXXXXXXXXX
remote: Enumerating objects: 124, done.
remote: Counting objects: 100% (124/124), done.
remote: Compressing objects: 100% (88/88), done.
Connection to bitbucket.org closed by remote host.
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: unpack-objects failed

Pulling on my local machine works without any problems so I suspect the problem is on the Yggdrasil side. Before the connection is closed by remote host I wait long seconds or even minutes staring at my terminal.

Kind regards,
Maciej
