[Bug 436392] Re: systemsettings crashed with AttributeError in maintenance_command() after "clean printer heads" button is pressed

[Bjoern Kahl]

Still unresolved, happens with fully up-to-date Ubuntu-Precise on x86_64

Looking at the code, the problem seems that the code in function
"maintenance_command" in file /usr/share/kde4/apps/system-config-
printer-kde/system-config-printer-kde.py, is out-of-sync with the user
interface description in file /usr/share/kde4/apps/system-config-
printer-kde/system-config-printer.ui.

The code in "maintenance_command" tries to style a non-existent label
"lblInfo" and then to show a non-existent dialog "InfoDialog" with both
do not exists in the loaded user interface file.

A work-around is to comment the offending code, but of course  that is
not a real solution.  The real solution would, to figure out why and
when application code and UI description diverted and to build a new,
consistent version of both.

Note:
There are many references to an "InfoDialog" or an "ErrorDialog" throughout the code, typically in the "except" part of "try ... except" blocks.  A few places use "KMessageBox.information(...)" instead, which seems to work.
