I cannot test that myself as the symbolic toolbox isn't available for
Linux systems.

When, though, I test it in maple directly, maple quickly returns:

[6^(1/3), ...
 -1/2*6^(1/3)+1/2*I*3^(1/2)*6^(1/3), ...
 -1/2*6^(1/3)-1/2*I*3^(1/2)*6^(1/3)]

Maple would run the int() before attempting to solve(), so this
is equivilent to asking maple to solve(k^3/3=2)
