Do you use KDE's mail user agent KMail? Do you use it with IMAP? If you do, you may be aware of various error messages such as ‘Unable to stat resource’.
For the benefit of people looking for a solution using search engines, the top few lines of the error message read something like this:
Error while getting folder information.
Could Not Determine Resource Status
An attempt to determine information about the status of the resource INBOX.customflags,
such as the resource name, type, size, etc., was unsuccessful.
