Partition Manager Crashes

[Miykel]

G'Day; I'm trying to install Ubuntu 12.04 onto it's own partition, alongside W7 and Ubuntu 11.10 but when I get to the point where I choose which partition to install to the partition manager crashes, no error number but the log files says "ubiquity crashed" any ideas ??
