Ember crashes when connecting to new Cyphesis server

[Olek Wojnar]

I have been experiencing Ember crashes while testing Cyphesis 0.6.2. To troubleshoot, I installed everything using the hammer script and tested again. Ember 0.7.2 crashed without any errors but the development version of Ember 0.8.0 gives the following error when it crashes:

ember.bin: /hammer/work/local/include/OGRE/OgreAxisAlignedBox.h:695: Ogre::Vector3 Ogre::AxisAlignedBox::getCenter() const: Assertion `(mExtent == EXTENT_FINITE) && "Can't get center of a null or infinite AAB"' failed.
Crashed with signal 6, will try to detach the input system gracefully. Please report bugs at https://bugs.launchpad.net/ember
Aborted

This occurs when a new character is created on a fresh server (database was created and cyloadrules was executed, nothing else) and the "Create" button is pressed.

Cyphesis was running in the foreground and showed the following:

2018-02-08T14:47:37 WARNING Error when writing to socket: (system:32) Broken pipe

We've made substantial changes to the core protocol, so older clients should not be able to work with newer servers, and newer clients will not work with older servers. However, the newest client version should of course not crash when entering an old server, it should just disconnect.
