Fix for wrongly labelled message in Ubiquity (Bug #1265192)

[Sebastian Philipp]

Hello,

please have a look at the newest developments on the bug #126512 
"Install/reinstall wipes out all/other partitions" 
(https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1265192). The 
leader of the Linux Mint project fixed the bug for Linux Mint 17 (based 
on Ubuntu 14.04). As this is a rather critical bug, I ask you to apply 
and test it on Ubuntu's version of Ubiquity ASAP so further data loss 
because of a malformed information stops.


Thanks in advance,

Sebastian Philipp,
victim of bug #1265192
