I switched the default window manager back to Compiz and LibreOffice behaves once again. Apart from changing the refresh rate to match my LCD display (60hz), everything is running tickety-boo. I will update this thread if I note any changes. It may well be that Compiz Fusion is the difference maker in this scenario. Yes, I have also set Compiz Fusion to launch at log in.

Okay, there's been rather a bit of chatter about Linux Mint Cinnamon and MATE freezing when launching LibreOffice, and I have read these topics. The symptom that caught my attention has been LibreOffice halting at the splash screen which seems more severe than most. This symptom was not evident until I enabled Compiz as the default window manager, with the understanding that it does not work out of the box, as stated by the Mint devs. Risks understood. ^^
The behaviour persisted even after numerous setting changes. Compiz clearly needs to be updated, but unfortunately I'm not the geek for that task. I tried installing LibreOffice Beta 3.5.5, but found my system halted at the depacking of liboffice-dict-en-us.deb in the terminal window. Had to resort to ctrl-alt-del to quit the session. Tried two more times, removing the previous install each time with package manager. Same result.
Here's the wrinkle: I found that launching the Compiz Fusion Icon and changing the default window manager to "MetaCity" completely resolved the issue. LibreOffice appears to be completely stable.
I must add to this that my system has halted in the very same manner with LibreOffice, Inkscape and GIMP in various circumstances. I presently have a bug listed on Launchpad related to the Inkscape issue, with no confirmation as yet. It's a rare bug, apparently. Mind you it only occurred in Cinnamon, and not MATE. I have isolated the system halts to Compiz, and apparently Compiz's own window manager. This system has run Linux Mint 12, Mint 13 Cinnamon and is right now running Mint 13 MATE.
I'd like to stress that this appears to be an issue with Compiz on Mint 13 Maya, and that the system halts are all symptoms. From the posts I've read there are some workarounds, but I have to pin this on Compiz. Unfortunately it's the fastest Window Manager out there that I am familiar with (I'm a newbie, to be sure), especially for slightly older hardware.
If you are experiencing system halts in Linux Mint with Cinnamon or MATE and Compiz, try the alternative window manager. It may work for you, though I admit it does not feel as fluid.
Here is an edited system report for reference.

This is is not the result of an exacting troubleshooting methodology, rather a process of trial-and-error-until-my-system-is-stable approach.
So far so good.
