GoogleAppEngineLauncher: database disk image is malformed

I've written a small application for Google App Engine and each time I want to run my app I have the following error: 

*** Running dev_appserver with the following flags:
    --skip_sdk_update_check=yes --port=13080 --admin_port=8005 --clear_datastore=yes

sqlite3.DatabaseError: database disk image is malformed

When I run an other application I've created, I don't have any error. I tried some basic ideas:

Nothing worked. Any idea?

The default log database filename is log.db. It is stored in your app storage directory, which by default is located in your tempfile.gettempdir() directory, named appengine.[appname].[userid].

The appname portion takes the value from your app.yaml (look for the application entry), replaces : colons with underscores, and removes everything before the last ~ tilde (if there is any).

So if your app is called foobar and your username is jbj, the corrupted SQLite database is located in:

`python -c 'import tempfile;print tempfile.gettempdir()'`/appengine.foobar.jbj/log.db

On Mac OS X, tempfile.gettempdir() returns a hashed path under /var/folders somewhere; it is simply taken from the TMPDIR environment variable, so you should just be able to use:

rm $TMPDIR/appengine.foobar.jbj/log.db

You can safely delete this file, it'll be re-created the next time you start the app.
