With the latest pushes to the master branch, I have noticed that I cannot run a notebook without the kernel crashing repeatedly. I do not have this problem on my Windows machine. \r\n\r\nI've isolated the problem to a commit (a87685b918bbd283b7893d56e25ce1b451567d4d) adding traits to the component class. The behavior is very strange as there is no output to the JS console, or to the bash console, other than the following: https://gist.github.com/jat255/d4b6347cf3b717b2a532.\r\n\r\nTo diagnose this, I completely deleted my local files, cloned the repo fresh, and went commit by commit, doing a hard reset of my working tree to each one, and this commit is the first one that causes the crash. It occurs only when opening an existing or creating a new notebook. i.e. there are no errors when the server is started or when it is not serving any notebooks. I am not sure why this error is not seen when running on windows. The related packages are the same on each system (as shown through pip) and are the following:\r\n\r\n1. ipython: 2.4.0-maint (installed through pip -e ./ from github)\r\n1. traits: 4.5.0 (latest version, installed through package manager in linux, and through python(x,y) on windows)\r\n1. traitsui: 4.40 (latest version, same as above)\r\n\r\nIs there any way I could go about debugging this further and figuring out the reason for the kernel crashing? I'm not sure how to get more output beyond \r\n\r\n    2015-01-18 12:35:31.022 [NotebookApp] WARNING | KernelRestarter: restart failed\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/hyperspy/hyperspy/issues/comments/124036311","html_url":"https://github.com/hyperspy/hyperspy/issues/435#issuecomment-124036311","issue_url":"https://api.github.com/repos/hyperspy/hyperspy/issues/435","id":124036311,"user":{"login":"francisco-dlp","id":989719,"avatar_url":"https://avatars.githubusercontent.com/u/989719?v=3","gravatar_id":"","url":"https://api.github.com/users/francisco-dlp","html_url":"https://github.com/francisco-dlp","followers_url":"https://api.github.com/users/francisco-dlp/followers","following_url":"https://api.github.com/users/francisco-dlp/following{/other_user}","gists_url":"https://api.github.com/users/francisco-dlp/gists{/gist_id}","starred_url":"https://api.github.com/users/francisco-dlp/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/francisco-dlp/subscriptions","organizations_url":"https://api.github.com/users/francisco-dlp/orgs","repos_url":"https://api.github.com/users/francisco-dlp/repos","events_url":"https://api.github.com/users/francisco-dlp/events{/privacy}","received_events_url":"https://api.github.com/users/francisco-dlp/received_events","type":"User","site_admin":false},"created_at":"2015-07-23T09:49:08Z","updated_at":"2015-07-23T09:49:08Z","body":"@jat255, does #584 fix this issue?"}}
