Dear Bellec,

 Thank you for your kind and quick reply.
 My host computer itself is based on Ubuntu 12.04 LTS. Since my environment was constructed NITRC-CE (http://www.nitrc.org/plugins/mwiki/index...) and it's not compatible with Ubuntu 14.04 or later, I'm trying to use NIAK with docker on Ubuntu 12.04.

 The crash occurred just after I run 'docker_run_niak', the some messages 'Welcome to Octave!' appeared and push 'Finish' button on Octave.

Best,
 Yuki
