Gitkraken doesn't show branches and commits

Ran into this because I had to check out my repo with limited depth. Cloning the repo fully ran into a closed connection, so I checked out a shallow copy:

git clone http://github.com/large-repository --depth 1

But this resulted in GitKraken omitting the history like what you ran into. GitKraken didn't handle the depth nicely; in order to fix it, I had to run this after the initial clone:

git fetch --unshallow

Update: I'm not sure if this was the same situation as what you ran into, but the GitKraken dev team responded to me saying the app doesn't support shallow copies yet: Why Gitkraken does not display any logs in big repos?
