Mae amgylcheddau Unix fel arfer yn gallu cysylltu ffeil neu plygell i enw a/ neu lleoliad sy' n wahân. Mae KDE wedi datgelu cysylltiad neu gyfres o gysylltiadau sy' n creu dolen ddiddiwedd - h. y., roedd y ffeil wedi ei gysylltu (efallai mewn ffordd cylchfannol) i' w hun.
UNIX environments are commonly able to link a file or folder to a separate name and/ or location. KDE detected a link or series of links that results in an infinite loop - i. e. the file was (perhaps in a roundabout way) linked to itself.
