#4 Plug-in Crashes after install in 13.1.3

[Steve Hummingbird]

Within IntelliJ 13.1.3 the plug-in crashes after the IDE is restarted after the plug-in installation. In case the plug-in is actived again and the IDE restarted, this is reproducible.

Plugin 'IDEA Doc' failed to initialize and will be disabled. Please restart IntelliJ IDEA.
