I've just noticed that class comments have stopped working in Pharo since I upgraded from Xubuntu 12.10 to Xubuntu 13.04. If I make any change to a comment or add a new comment I get an error in RemoteString - 'RemoteSring past end of file'. This happens both for Pharo 2.0 images and older Pharo 1.4 images. It happens if I add comments to new classes or to classes where I have previously successfully added comments. This is where it falls down: string "Answer the receiver's string if remote files are enabled. Use a read only copy to avoid syntax errors when accessed via multiple processes." | theFile | (sourceFileNumber == nil or: [(SourceFiles at: sourceFileNumber) == nil]) ifTrue: [^'']. theFile := (SourceFiles at: sourceFileNumber) readOnlyCopy. ^[filePositionHi > theFile size ifTrue: [ self error: 'RemoteString past end of file' ]. theFile position: filePositionHi. theFile nextChunk] ensure: [theFile close] Anyone else seen this? Anyone got a solution? Ken
