Fatal error: Call to a member function delete() on a non-object in xxx/views/views.module on line 1550

I get this error when I try to revert views that have been exported to a feature. This is causing a serious problem for us as we cannot revert out views to our production system.

My views are in my feature. However when I revert, I get the fatal error. When I do a drush cc all - the error disappears and the view is in list of views. If I do another drush cc all (nothing else) the views disappear from the list (database)

Attached sequence, screen shots and feature.

Screen shot 1 shows the views are not in the list

$ drush fr simplybiz_job_spheres
Do you really want to revert views_view? (y/n): y

Reverted context. [ok]

Notice above that I'm not asked if I want to revert the views. Screen shot 2 shows the views are now in the list

$ drush cc all
'all' cache was cleared

Screen shot 3 shows the views have disappeared again
