Comment 1 Tim Lauridsen 2010-01-26 10:29:41 UTC

I can reproduce the issue, but it is not normal operation to Cancel the root password prompt, yumex is starting a background task running as root using consolehelper, so if you cancel the root password, the gui will wait forever for the background task to be loaded and you will see the high CPU usage count.
The right action will be to alert the user and quit the gui.

Comment 2 Tim Lauridsen 2010-01-26 14:50:11 UTC

fixed upstream, so the gui will detect if the backend is not started, if someone is clicking on cancel on the root password dialog.

Comment 3 ebird98 2010-01-28 01:41:15 UTC

Ok, but I have a question:
Why To Ask for root passwd when starting yumex instead of as necessary?

Comment 4 Tim Lauridsen 2010-01-28 17:50:58 UTC

because the yum action is running as a background as root, so we need the root password when the backend is started. So the root password is needed right as the gui is started.
