           Product: LibreOffice
           Version: 5.0.6.3 release
          Hardware: All
                OS: All

Description:
_CxxUnregisterExceptionObject VCRUNTIME140 after _RTDynamicCast related to
SwViewShell::SetEndActionByVirDev

Steps to Reproduce:
1. open the attached file
2. Go to page 18
3. Enter the page + press backspace
4. Delete the page break 

Use very sleepy (or a flame graph) to see what's being done

Actual Results:
30% of 10 second time frame spend in CxxUnregisterExceptionObject (did only a
partial trace) 

Expected Results:
An exception doesn't sound optimal & spending a lot of CPU time in it (making
stuff slow) makes it worse


Reproducible: Always
