Hi,

When loading "Pier-Pharo-Persistency" in a Pharo 1.4, the following warning is raised:

This package depends on the following classes:
  ImageSegment
You must resolve these dependencies before you will be able to load these definitions:
  writeKernel:on:

Select Proceed to continue, or close this window to cancel the operation.

This is due to a reference to ImageSegment in the following method:

PRSegmentPersistency >> serialize: aString
    | stream pointers |
    stream := self directory forceNewFileNamed: aString.
    pointers := [ [ ImageSegment new writeKernel: self kernel on: stream ]
        ensure: [ stream close ] ] on: Exception do: [ :error | nil ].
    (pointers isNil or: [ pointers anySatisfy: [ :each | (each isLiteral or: [ each isVariableBinding ]) not ] ])
        ifTrue: [ self directory deleteFileNamed: aString ifAbsent: [ ] ]

Would this be worthy to fill a bug report?

Cheers,
Reza
