This issue has sat with a status of 'Incomplete' for more than 10 years now without any response so it is being closed as 'Fixed Released' as no-one has posted any comments to suggest the report is still valid and I haven't experienced any issues myself when installing Ubuntu which I always do after selecting the manual partitioning option.
Please feel free to re-open this bug report if this is still an issue when using a currently supported release of Ubuntu and tell us in which release you still experience this issue.
