Thank you for taking the time to report this issue and help to improve Ubuntu.
As of Ubuntu 8.04, the smbfs driver is obsoleted in favor of the cifs driver (due to a number of unresolved bugs in the smbfs driver, including this one). Therefore, I believe this issue can be considered resolved for 8.04. If you experience other issues with the cifs driver, please feel free to open new bug reports about those problems.
