Hi,
When a snapshot file reading fails in ImportSnapshot(), it errors out
with "invalid snapshot identifier". This message better suits for
snapshot identifier parsing errors which is being done just before the
file reading. The attached patch adds a generic file reading error
message with path to help distinguish if the issue is with snapshot
identifier parsing or file reading.
