[deleted - test.q uses the MASS function glmmPQL
and runs just fine. Some output is written to a 
 structure I wish to save]

> q()
Save workspace image? [y/n/c]: y

[martingale <101>]% R

Error: object 'family' not found whilst loading namespace 'MASS'
Fatal error: unable to restore saved data in .RData


If I simply remove .RData, start up R, load the indicated libraries,
and quit & save, I can start R up again with no problem.
