Comment 2 for bug 792118

Added check whether a file exists during startup and adding to history. Clipboard items which have a reference to a file, which does not exist anymore will not be added to the history and therefore this error should not occur anymore.

However when there is a file which exists but for whatever reason the mime type can not be figured out, it will log a warning and fallback to the mime type text/plain (which is then used to show the appropriate icon in the indicator or lens).

Should be soon available in the daily ppa.
