On Ubuntu 14.10 this still happens, and annoys me. It happens both on my laptop and my work desktop. Interestingly, Super+s and Super+w work fine even if I type them extremely quickly, but Super+a does not work and inputs 'a' to the focused application instead of opening the application lens. Analogous problems occur with Super+f, Super+m, Super+c and Super+v.
