After being able to install 1.5.9 on Ubuntu 14.04, when there is no deb file on SourceForge (thanks mytrant for the info re the use of alien to convert from rpm) I was disappointed to find that the bug which prevents a project which has baseline set from saving in xml is back. This is a bug which had been present in 1.5.7 and earlier  version but had been resolved in 1.5.8; although 1.5.8 had its own problems with resetting dates and durations if saved with a baseline! The only doubt I have re this bug is that could be a result of a glitch in the rpm to deb conversion via alien and not a ProjectLibre inherent issue. Have any other users on any OS found the same problem - on a new or existing project save a baseline and then try and save a copy of the project as an xml file. Does it complete the save and can you reopen the xml file or does it hang without completing the save?
