Comment # 8 on bug 1003528 from Olaf Hering

I suggest we just downgrade in Factory to 3.3 until the issue is understood.
According to the .changes file there is nothing which justifies the upgrade to
3.4+.
diff(1) from Factory also takes more than 10 minutes on a SLE_12 system.
diff(1) from SLE_12 takes around 3 minutes.
