I have installed pam-kwallet-5.4.2-1 from updates-testing. This version should be able to open both kwallet4 and kwallet5 at login. However 9 times out of 10 I am still asked for a password for kwallet4 on login. Kwallet5 is always opened without asking for a password.

Reproducible: Always

Steps to Reproduce:
1. Install pam-kwallet-5.4.2-1, kde-runtime-15.08.1-2.fc22.x86_64 (for kde4's kwallet), kf5-kwallet-5.14.0-1.fc22.x86_64 (for kf5's kwallet). Optionally also install kde4's and kf5's version of kwalletmanager for easy testing.
2. Make sure you use the same password for login, and the default wallets in both versions
3. Log in to the system and verify which wallets are opened automatically


Actual Results:  
On my system, kf5's default wallet is always opened, while kde4's default wallet isn't. I remember it worked a couple of times early on.

Expected Results:  
Both default wallets should be opened at login.

I have tested this with a recent version of sddm (0.12..0-5). I am aware old versions won't work.
