Most icing incidents arise from ice accumulating on an aircraft inflight, not on the ground. Turboprops generally are more susceptible to icing than jets because they tend to fly lower where there's a better chance of encountering icing conditions. They also tend to fly slower, which makes it easier for the ice to "stick" to the airframe.
As
bhmlurker pointed out, after
this crash in 1994 some airlines actually moved turboprops out of cold weather locations. But even sticking to warmer areas doesn't guarantee an ice-free flight: in 2006
a commercial turboprop flight out of SBP dropped several thousand feet after encountering severe icing over the coastal ranges on the way to LAX.
