What happened was that I did not explicitly state the webapp2 version in app.yaml, and then dev_appserver (without any notice/warning/error) just used version 2.3. Explicitly stating version \"2.5.2\" gave the correct stack trace dump in browser. Personally I would have expected either an import error (preferrably) or at the very least a warning on the terminal when starting the dev\\_appserver.py script\n\nRun\n---\n    dev_appserver.py debugTrueBugInWebapp2\n\n.. then point your browser to http://localhost:8080.\n\nThe expected behaviour is for the browser to print a stack trace.\n\nWhat is really happening is that the stack trace is shown in terminal window, and the browser shows a blank page.\n\n\nEnvironment\n-----------\n\nI'm on an Ubuntu14.04-64 bit system with default Python2.7 installation, using latest version of Google App Server.\n\nDetails:\n\n    $ cat /etc/*-release\n    DISTRIB_ID=Ubuntu\n    DISTRIB_RELEASE=14.04\n    DISTRIB_CODENAME=trusty\n    DISTRIB_DESCRIPTION=\"Ubuntu 14.04.1 LTS\"\n    NAME=\"Ubuntu\"\n    VERSION=\"14.04.1 LTS, Trusty Tahr\"\n    ID=ubuntu\n    ID_LIKE=debian\n    PRETTY_NAME=\"Ubuntu 14.04.1 LTS\"\n    VERSION_ID=\"14.04\"\n    HOME_URL=\"http://www.ubuntu.com/\"\n    SUPPORT_URL=\"http://help.ubuntu.com/\"\n    BUG_REPORT_URL=\"http://bugs.launchpad.net/ubuntu/\"\n\n    $ python -V\n    Python 2.7.6\n\n    $ which dev_appserver.py \n    /home/olof/google_appengine/dev_appserver.py\n    \n    $ cat /home/olof/google_appengine/VERSION\n    release: \"1.9.17\"\n    timestamp: 1415734244\n    api_versions: ['1']\n    supported_api_versions:\n      python:\n        api_versions: ['1']\n      python27:\n        api_versions: ['1']\n      go:\n        api_versions: ['go1']\n      java7:\n        api_versions: ['1.0']\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fobjarni%2Fdebugtruebuginwebapp2","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fobjarni%2Fdebugtruebuginwebapp2","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fobjarni%2Fdebugtruebuginwebapp2/lists"}
