git hangs after "Resolving deltas"

Have had a funy problem with Git. I suppose it's proxy-related. Writing it down, because sure that will have the same problem some time again. Also hope it will help to people who are also suffering with it.

As a precondition, I have a git with following in '.gitconfig':

[http]
proxy=http://user:password@proxy:8080

When I tried to clone repository I've got this:

$ git clone https://code.google.com/p/caliper/
Cloning into 'caliper'...
remote: Counting objects: 3298, done.
remote: Finding sources: 100% (3298/3298), done.
remote: Total 3298 (delta 1755)
Receiving objects: 100% (3298/3298), 7.14 MiB | 1.94 MiB/s, done.
Resolving deltas: 100% (1755/1755), done.

And then nothing, it just hangs. If you go and have a look, you can see that files are downloaded, but not unpacked. As all other people on Internet, I have no idea why that is happening, but eventually I have found a way to get files out of it.

When it hangs, just kill the process with Ctrl+C and run this command in repository folder:

$ git fsck
notice: HEAD points to an unborn branch (master)
Checking object directories: 100% (256/256), done.
Checking objects: 100% (3298/3298), done.
notice: No default references
dangling commit 2916d1238ca0f4adecbda580ef4329a649fc777c

Now just merge that dangling commit:

$ git merge 2916d1238ca0f4adecbda580ef4329a649fc777c

and from now on you can enjoy repository content in any way you want.
