I've experienced the same behaviour. It is on a fresh install of 12.10. Potentially relevant packages installed include ccsm, advanced settings and the faience theme. The jumping of the columns seems to stop if the widths are changed but if the view is changed (Ctrl+1) and changed back (Ctrl+2) the strange behaviour starts again. It's mainly a problem when right clicking but still happens with the left click.
It seems a minor issue but is very noticeable and I most often use the list view with lots of files.
