I am getting this error message occasionally : ERROR : corrupted list.gum file
What is the list.gum file ? How does it become corrupted ? How is this fixed ?
out of curiosity: What device / kind of hardware do you use?
Corruption may be defined as "file does not contain what it is supposed to contain". Just guessing: Maybe the file got corrupted in a crash situatiom, maybe flash storage is defective, and so on.
