parted_server crashed with SIGABRT in ped_assert()

[Max Brustkern]

Reproducible on Ubuntu Trusty Desktop 20140413 AMD64, Ubuntu Gnome, Kubuntu.

TEST CASE:
1. Prepare a GPT or MSDOS disk with 1 primary partition of type FAT32 which uses all disk space.
2. Boot in EFI or BIOS mode from an Ubuntu Trusty Desktop AMD64 ISO with this disk attached
3. Launch Ubiquity from the live session
4. On step 'Prepare' press 'Continue'

ACTUAL RESULT:
parted_server crashes with the following trace in syslog:
Backtrace has 9 calls on stack:
  9: /lib/x86_64-linux-gnu/libparted.so.0(ped_assert+0x31) [0x7ff39159e4b1]

and a unreadable error dialog.

Retraced stack trace attached to bug 1307175

== Original Description ==
I've got the daily kubuntu amd64 desktop image on a usb stick, booted via grub2. When I get to the part where the installer wants to unmount partitions, I get an unreadable error message, and the installer sits on "Preparing to install Kubuntu" with the Back and Continue buttons greyed out.

Here is the crash file.

[Max Brustkern (nuclearbob)]

I've recreated this on today's ubuntu image as well. I didn't notice it on ubuntu images earlier this week using the same procedure, so it may be something new.

[Phillip Susi (psusi)]

Can you run sudo parted -l?

[Max Brustkern (nuclearbob)]

Confirmed on i386 as well. Here's the output of parted -l:

[Rod Smith (rodsmith)]

FWIW, the problem also occurs on BIOS boots and with MBR partition tables, not just EFI boot with GPT.

[Colin Watson (cjwatson)]

Much simpler test case: "print NUMBER" in parted, where NUMBER is the partition number of a FAT-formatted partition on a local disk.

[Launchpad Janitor (janitor)]

This bug was fixed in the package parted - 2.3-19ubuntu1

---------------
parted (2.3-19ubuntu1) trusty; urgency=medium

  * Upload from Debian git repository to fix a release-critical bug.
  * Fix crash when opening FAT file systems (LP: #1306704).
