I have just checked in a major change to the Views API. Details can be 
found in the advanced help under api.html (and the handlers and plugins) 
pages, but the short version is that all handlers and plugins are now 
separated into their own files in order to conserve memory and not 
loaded unneeded code. This required implementing an API versioning 
system, and the upshot of this is that a new hook must be implemented by 
all Views modules: hook_views_api(). Without the proper use of this 
hook, the *.views.inc files will not be included.

If your module includes its *.views.inc files itself or keeps its 
handlers in the .module file, this is wrong and will cause sites to crash.
