Check_MK Werk 0354: Catch exception when check plugins do not return a state

ID: 0354 Title: Catch exception when check plugins do not return a state Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.5i1 When a broken check plugin does not return a proper state then Check_MK broke with an exception. This is now better handled. The check now goes into <i>UNKNOWN</i> state with the message <tt>Check plugin did not return any result</tt>.
