Mint 14 Cinnamon x86_64 live installer crashes trying to delete a Fedora LV

To reproduce:

1. Do a clean install of Fedora to a simple system with a single disk. Probably doesn't matter what build you use, I happened to be using F19 Beta TC4. Use Fedora's default disk layout, which uses LVM - it creates a single VG named 'fedora' and LVs for / and swap (and /home if you have a disk of 50GB or larger, but my test did not).

2. Boot linuxmint-14.1-cinnamon-dvd-64bit.iso . Launch "Install Linux Mint"

3. Continue till you reach the "Installation type" stage, click "Something else" and then Continue

4. Click the entry for the Fedora root or swap LV, and try to delete it

5. Dialog appears: "ubi-partman failed with exit code 141. 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."

This is 100% reproducible for me. Exit code 141 is 141-128 = 13 - SIGPIPE. Nothing is appended to /var/log/syslog at the point of triggering the crash, that I can see.
