Errors when wakatime.com is not responding.

[jamapag]

For some reason wakatime.com is not responding for me so vim plugin constantly writes errors on top of vim window, so I unable to work with it. There is some logs:

And it writes those 'Tracebacks' into my vim window.

Thought this was fixed with #39, guess it's still a problem in urllib3 master version.

[jamapag]

Is it necessary to print whole stack traces into vim window/std out?

[alanhamlett]

Can you update vim-wakatime and see if the error is fixed?

We should redirect tracebacks, but I haven't been able to redirect the output of exec to a variable yet.

[jamapag]

Problem still exists. You can test it by yourself. Just close internet connection, and try to open some file with command line vim. Result should be something like this:

[alanhamlett]

Should be fixed in the latest version of vim-wakatime. There was a problem with the cached requests.Session object when it was pickled from a previous version of requests that wasn't compatible with the latest version.

[jamapag]

Looks good for me.

Thanks!
