Do you keep your little digital camera in a heavy Zip-Loc bag to keep out dust, even inside the camera case?

I just bought a Canon PowerShot A530, which is nice generally but which seems notorious for being part of a family of entry-level Canon digital cameras susceptible to the dreaded ';E18'; error, apparently typically associated with dust or fine grit having gotten into the lens arrangement (the lens extrude automatically before the camera is ready to take pictures).Do you keep your little digital camera in a heavy Zip-Loc bag to keep out dust, even inside the camera case?
nope I never heard of doing that and moisture might actually form in the ziploc bag. Its better to get a bag like the one in the ebay auction below.

I never have...and I've never had a problem.
