The symptom is the same as described in bug 42673: an .ods file that opened without problems before now causes the application to hang for at least several minutes when trying to open it. Other .ods files can be opened fine.
In my case that hang appears to be related to a network printer that runs on a machine which I am not normally logged on to. After logging on through Windows Explorer, I was able to open the problematic .ods file normally.
Looking at the discussion on http://ask.libreoffice.org/en/question/18138/calc-hangs-on-opening-ods-file-some-days-some-days-not (after running into a similar issue with Libre Office 4.2.52 on Windows 8.1), I believe that bug 42673 was marked as "resolved" prematurely, as also indicated in comment #9 on that bug.
For what it's worth, there is also a reference to the printer in the settings.xml file inside the document (in <config:config-item config:name="PrinterName" config:type="string">).
Could you please provide a backtrace for this crasher as described in https://wiki.documentfoundation.org/How_to_get_a_backtrace_with_WinDbg? It would help tremendously in pinpointing the cause.
Set to NEEDINFO per comment 1.
Change back to UNCONFIRMED after you have provided the backtrace.
