N::meprec warning with Solve

consider the function:

f[x_] := (x^4 + x^3 + x^2 + 5)/(5 x^2 + 5 x + 5)


gives the warnings:

"Internal precision limit $MaxExtraPrecision = 50.` reached while
evaluating Im[61/(3\(<<1>> <<1>>)^(1/3))+1/3\ (1/2\(<<1>>))^(1/3)]."

How can this happen if no Reals are used? Why is N called?

BTW the results of Solve are correct
