Status changed to 'Confirmed' because the bug affects multiple users.

[Brian Murray (brian-murray)]

This happened to me immediately after booting a live usb stick with persistence and choosing try ubuntu.

[Doug McMahon (mc3man)]

Also happening on the 1/27 image when trying to install - message is "installer crashed", links to this report
(install fails

[Chris Peach (peachris+ubuntu)]

This is still happening in the 1/28 live i386 image after booting a live usb stick with persistence and choosing try Ubuntu (German locale, Dell D630 laptop).

[Chris Peach (peachris+ubuntu)]

PS: This crash occurred on the first and second start of the live system with persistence, but not on the third start (after installing some deb packages).

Also happening on the 1/28/2012 daily build of the live CD i386 image after booting and connecting to my wireless network. I've booted twice and it has occured each time.

[Chris Brody (chris-brody)]

See question 186142. When installing from CD, when I get the chance to select a wireless network, if I hit Back then Back again the installer is getting this crash.

[Rob Whyte (fudge)]

USB 64 1/30/2012 daily crashes both on install and from live desktop.
Installer proceeds up until where do you want to install Ubuntu page.
Selected something else/manual clicked forward and ubiquity crashes.

[Rob Whyte (fudge)]

Same problem when using a disk.
Problem seems to only be with manual partitioning.
When selecting side by side installation installer has no problems.
Did try to apt-get isntall --reinstall libparted with no futher success.
Also did note an error when apt-get update is performed.
Belive it is unrelated.

[Paul Bakulich (palbakulich)]

Installer wouldn't let me customize my partitions the way I'm used to.

Usually you get to choose which partition you want to be root, crashed soon as I asked for manual configuration.

[Jean-Baptiste Lallement (jibel)]

Reproduced with Ubuntu Desktop 20120130.
Boot to a Live Session from the ISO.

[Sebastien Bacher (seb128)]

The issue is an ubiquity one:

static const char* indicators[] = {
 "/usr/lib/indicators3/6/libsession.so",
 // Bluetooth
 "/usr/lib/indicators3/6/libapplication.so",
 "/usr/lib/indicators3/6/libsoundmenu.so",
 NULL
};

that directory needs to be updated for the current so version

Merge proposal created.
