Installing Daily live (2011-01-20) Natty Xubuntu on Virtualbox 4.0.2 for maverick amd64. Machine has dynamically expanding 8 GiB hard drive. Started live session and launched Ubiquity. Pressing "Forward" button on installation step "Preparing to install Xubuntu" a message popped - "This partitioner doesn't have information about the default type of the partition tables on your architecture. Please send an e-mail message to <email address hidden> with information. Please note that if the type of the partition table is unsupported by libparted, then this partitioner will not work properly." with options to "Go Back" and "Continue". I pressed latter. Then popped another message - "ubi-partman failed with exit code 10. Further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken." with options to "Quit", "Continue anyway" and "Try again". I pressed to continue. I got in next steps as far as entering my new username password and pressing "Forward". Then installer closed itself. Then i reset the virtual machine. Started live session again and first thing - opened GParted and created msdos partition table. Then started Ubiquity again. Nothing had changed - same two warning messages. Then on keyboard selection step I pressed "Quit", it closed and Crash report icon appeared, which I used to get here.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

I am able to reliably reproduce this issue when installing from the Live environment. Although Ubiquity crashes during the installation, it does complete installing.

This was the bug fixed in partman-partitioning 78ubuntu2 (ubiquity 2.5.11):

partman-partitioning (78ubuntu2) natty; urgency=low

  * Support archdetect being anywhere in PATH rather than assuming it to be in
    /bin. It's moved locations in archdetect-deb.

I've confirmed that this is no longer happening on a current Xubuntu i386 daily-live build, and other Xubuntu architectures also seem to have a sufficient version of ubiquity.
