Interesting. There must be some caching involved. If print(a) is
resolved to print.mixfitEM at least once, it keeps failing. In a fresh
R session, where a trace()-patch is done before printing objects of
this class, print(a) succeeds:

trace(mixR:::print.mixfitEM, quote({ mc$x <- x }), at = 7)
(function(a) print(a))(fit1) # this used to fail
# Tracing print.mixfitEM(a) step 7
# Normal mixture model with 2 components
#        comp1     comp2
# pi 0.2977772 0.7022228
# mu 2.0140197 4.9837052
# sd 0.8896020 1.0273591
