--- Comment #29 from NISZ LibreOffice Team <libreoffice at nisz.hu> ---
Oh, I can confirm this :).

* Take a known document and steps to crash LO. I used the one in bug 126226 and
steps to make it crash (now this one got fixed in master, but any known crash
can be used. This bug bothered me for months before finding how to reproduce.).

* Document recovery kicks in, and offers to restore the document. 
* Choose Discard here, this is the most important.
* Load the document again and make it crash again.
* This second time the recovery won't kick in, but LO keeps the processor 100%
loaded. Only way to stop it is to kill via Process Manager.

I bibisected this to the same range as comment #18:
