Application Error but claims successful exit

I just stumbled upon this log from DaVinci:

https://lhcb-analysis-productions.web.cern.ch/pipelines/?id=6201119&prod=Bd2Dpi_Run3&job=Bd2Dpi_Collision23_Down

It looks like it should have been a fatal error:

EventSelector.DataStreamTool_1         INFO Compression:8 Checksum:1
EventSelector.DataStreamTool_1        ERROR Cannot read 1953460062 bytes of uncompressed data.

EventSelector.DataStreamTool_4         INFO Compression:12 Checksum:1

But the application exits succesfully;

ApplicationMgr                         INFO Application Manager Finalized successfully
ApplicationMgr                         INFO Application Manager Terminated successfully

And the summary XML also claims everything is okay:

	<success>True</success>
