Whenever, I run muon/updater 2.2.0, I notice the blue progress bar not behaving in a linear fashion as the updates are downloaded and installed; instead, a narrow blue bar continuously moves back and forth across the progress bar field until. It NEVER provides ANY useful information regarding the completeness of the download- or install-process; instead, it always leaves me guessing as to how much longer they are going to take. VERY FRUSTRATING! However, I experienced no problem whatsoever with the older version of muon-updater that is included in Kubuntu 12.04 LTS; that version of muon works perfectly. This is the reason why I went back to 12.04; I thought this problem would be fixed by now, but I guess I was wrong.

Reproducible: Always

Steps to Reproduce:
1. Click on update manager in System Tray, or select from KDE menu in System Tab.
2. Enter root password.
3. Observe the blue progress-bar as updates are downloaded and then installed.

Actual Results:  
A narrow, blue progress indicator simply moves left and right repeatedly, instead of growing towards the right in a linear-manner as the updates are downloaded; ditto for the installation progress-bar.

Expected Results:  
The progress-bars should have grown in a linear-manner to indicate percent-completed; that is what they are there for.

I am running Kubuntu 14.04 LTS on a 20-inch iMac5,1 (late 2006); I believe this to be irrelevant, but I will mention it anyway.
