screenshot of error message.

Description of problem:
Error dialog is shown with no information on the source of the error.

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

How reproducible:

Steps to Reproduce:
1. machine upgraded from F10, updates, F11Preview, rawhide,
2. set boot line to runlevel 3
3. login as root (yes, I know)
4. startx into gnome desktop
5. start doing some tests, a minute or two later...

Actual results:
Over the top of the app I was working in is shown a dialog:
An internal system error has occurred.
! An internal system error has occurred.
A problem that we were not expecting haas occurred.
Please report this bug in your distribution bugtracker with the error description.
More Details: 
Spawn of helper '/usr/share/PackageKit/helpers/yum/yumBackend.py' failed

Expected results:
Clearer error message on the cause, and source of the message; not failing.

Additional info:
The machine seems to be ignoring the dhcp server provided nameserver ip, leaving the machine with operating ip protocol, but no name resolution. Not sure yet whether solving the name resolution problem makes this issue go away.

Well, it's an internal error, as it's not supposed to ever happen! :-)

If you run "NETWORK=TRUE /usr/share/PackageKit/helpers/yum/yumBackend.py get-updates none" in gnome-terminal, what does it say?
Comment 2 Andrei ILIE 2012-11-18 12:42:52 EST
Confirming this against Fedora 17, PackageKit v0.7.5. Please see the attached screenshot.

$ NETWORK=TRUE /usr/share/PackageKit/helpers/yum/yumBackend.py get-updates none
