second (non-admin) user cannot change profile picture

[Daniel Kessel]

Trying to provide all details that may matter:
The system is installed in English. The first (admin) user also has English set as language.
The system has a second (non-admin) user, which has German language settings.

After selecting a new profile image from the hard disk and clicking "Apply", the password confirmation dialog pops up. It does not accept the user's password, and also not the administrator's password.
