NullReferenceException when logging with ApplicationInsightsBackend

I have a project that uses the ApplicationInsightsBackend to log various things.

When logging an exception i get another exception (NullReferenceException) with the following stacktrace:
at PostSharp.Patterns.Diagnostics.Backends.ApplicationInsights.ApplicationInsightsLogRecordBuilder.SetExecutionTime(Double executionTime, Boolean isOvertime) at My.Logging.Class

No idea what goes wrong, but if i switch to the ConsoleLoggingBackend everything works (and no thats not an option).

Its version 5.0.44 btw.

    this is a bug of ApplicationInsights backend. As a temporary workaround you should disable ExecutionTime logging in your logging profiles.

    (internal issue #15877)

    We will be working on a fix.
