Bug 702784

Description of problem:

F14 system behind firewall and uses proxy to access yum repositories. Usually don't see update notification in tray unless I do a "yum clean all" after the previous update. Also kpackagekit will not do updates when commanded due to "waiting for other application" (which may be zombie yumBackend.py that I usually see, not sure). Yum update always works but sometimes have to do yum clean all before yum update sees anything.

This was a fresh install of F14 on system that uses proxy access. Have another system that I upgraded from F13 to F14 that always works fine doing automatic updates or update requests from kpackagekit and directly from yum that never requires a yum clean. However, this other system uses direct connect to internet with no proxy.

Version-Release number of selected component (if applicable):

Fully updated (no testing or rawhide) f14 kde 4.6.2 system, x86_64


How reproducible:


Steps to Reproduce:
1. On system using proxy, don't see updates in tray after many days.
2. Run kpackagekit and check for updates
3. Seem to wait for "other application" too long. Exit kpackagekit using by 
closing window with "x" Also, sometimes it claims it need authentication but there is no prompt for authentication.
4. Run sudo yum update and usually finds update but sometimes have to do 
"sudo yum clean all" first.
5. After yum update, if do yum clean I see new updates OK in tray and can update by clicking on icon there when new updates available. If I don't do yum clean, the problem seems to arise.
  
Actual results:
Only get updates with yum update not with kpackagekit.


Expected results:
Should be able to get updates automatically using tray icon and never need to run yum update or do yum clean. Works as expected on f14 system with direct connect to internet, bad on other system using proxy connection to yum repositories.


Additional info:
Main difference between system that works OK and on that does not is OK system uses direct connect and system that has this problem uses proxy connect.
