I am experiencing frequent crash/hang of LO 4.4.2 in Ubuntu 14.04. Sometimes cell having correct formula is returning error (like err522). Is it me only?.

What PPA (the link) do you get the packages from ?

@rautamiekka. I get the packages from ppa:libreoffice/libreoffice-4-4 ie, http://ppa.launchpad.net/libreoffice/libreoffice-4-4/ubuntu

Have you tryed resetting user profile? https://wiki.documentfoundation.org/UserProfile.

Sounds like either corrupted installation or corrupted compilation.
