terraform crashes at first plan (not apply)

[deknos]

Hi, my opentelekomcloud plugin with terraform crashes these days. it worked at one point. i also submitted that crash to terraform, but i have the feeling, the otc plugin is the problem, here my description:

$ terraform -v
Terraform v0.11.7
+ provider.openstack v1.7.0

Terraform Configuration Files

my configuration files are in http://gbks.net/tf.zip (about 20kb size) without credentials of course :> i use the opentelekom cloud plugin. i am not entirely sure if this is the right bugtracker or if i should go to opentelekomcloud plugin..

Debug Output
