fdo#47466 FORMATTING: Autoformat empty rows causes app to crash

Thank you John LeMoyne Castle for your support
http://nabble.documentfoundation.org/Wrong-indentation-which-leads-to-segfault-in-sc-source-ui-docshell-docfunc-cxx-td4026726.html
However, the weird thing is I reproduced the crash with master sources but didn't with 4.0 branch nor with 3.5.4.2 Debian packages
