plugin does not work correctly with custom ssh port

[v1co1n]

I got this error in my production log, when i press apply button on git_hosting plugin page.
There are no errors in git_hosting.log , and everything seems to be ok, but apply button not working.
And the same error im getting everytime i try to do some changes to gitolite repositories in my projects.
