[Bug 1080445] Re: Lubuntu full disk encryption password quality check on installation is confused by (

Confirmed in Xubuntu 12.10.

Leaving out the brackets does not solve the issue. I thought this was an
issue with special characters however:

Composing a password exclusively from special characters works fine...
E.g., !@#$%^&*()_+

Adding a regular character to the above string is also fine but the
second regular character triggers the bug.

!@#$%^&*()_+1 = 'Strong password'
!@#$%^&*()_+11 = 'Short password'

And as the original submitter mentioned any strong password that becomes 'short' will fail to unlock the volume with the error:
'cryptsetup: cryptsetup failed, bad password or options?'

Title:
  Lubuntu full disk encryption password quality check on installation is
  confused by (

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Installing from lubuntu-12.10-desktop-i386.iso in VirtualBox, select
  Encrypt the new Ubuntu Installation...  When entering the security key
  is requested, and as one types it a quality indicator appears to the
  right of the input box

  Adding an open bracket to a strong password, however, seems to confuse
  the quality checker, for instance:

  Entered			Displayed
  abcab			weak
  abcab1			fair
  abcab12			good
  abcab12#$		strong
  abcab12#$(		short

  Furthermore, after using the final password, I am not able to mount
  the installation, as it complains of a bad passphrase.
