I have been using Ubuntu since release 7.x and switched to the light version (Lubuntu) at version 10. or so. Now I am on Lbuntu 12.10 (quantal).
With 12.04 LTS I also had some random crashing issues (Mostly in Firefox & Thunderbird). After doing a force upgrade away from 12.04 LTS to 12.10 via sudo apt-get update && sudo apt-get upgrade the crashes stopped.
A few week after that change the crashes are gone still with no new 'pain' points from the 12.04 to 12.10 upgrade.
