Warnings 'Enablement expression' when debugging an application

Symptom in a Neuron Power Engineer version < 3.11.0: If you switch to the perspective Debug (see "Debugging application in perspective "Debug""), the following warnings are displayed in the Error Log view:

Enablement expression is missing for descriptor type org.eclipse.cdt.debug.core.coreBuildDescriptorType

Enablement expression is missing for config provider for org.eclipse.cdt.debug.core.coreBuildDescriptorType

or

Warning: Enablement expression is missing for config provider for org.eclipse.cdt.dsf.gdb.gdbRemotedescriptorType | Plug-in: org.eclipse.launchbar.core 

Warning: Enablement expression is missing for descriptor type org.eclipse.cdt.dsf.gdb.gdbRemotedescriptorType | Plug-in: org.eclipse.launchbar.core

Cause: These warnings are Eclipse-internal messages. Usually, the warnings do not influence the operation of the perspective Debug.

Solution 1: Use the Neuron Power Engineer version 3.11.0 or a subsequent version. The messages will not be displayed when using such a version, 

Solution 2, if you are using a Neuron Power Engineer version < 3.11.0: Ignore these warnings. Use the perspective Debug as described under "Debugging application in perspective "Debug"".
