Can a bad SanDisk cause color distortions (red hues) in Canon PowerSho

Wife has a Canon PowerShot s60 that has produced images with reddish hues. They remind me of the coloring problems shooting film in various light sources (e.g. tungsten, flourescent, etc.)

Also, some of the objects in the images seem give off a bright glare that makes the object look like it's melting.

Changed out the memory card (a SanDisk 1.0 GB CF) for the original Canon card and the problem ceased. I fail to see the connection, however.

Could it simply be the SanDisk and not the camera? My wife has used the SanDisk card successfully for more than a year now.

Any ideas?
