Insufficient access permissions for qt_plugins_3.3rc
Last modified: 2008-07-15 15:19:56 UTC
When setting up a newly installed openSUSE 11.0 RC1 system (with KDE 4.0), I brought up Konsole to look around, check, and set up various components. I invoked hp-toolbox from the command line, and although it appeared to come up properly, it did emit a complaint from QSettings: bayard@(none):~> hp-toolbox HP Linux Imaging and Printing System (ver. 2.8.4) HP Device Manager ver. 13.1 Copyright (c) 2001-8 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY.

QSettings: failed to open file '/usr/lib/qt3//etc/settings/qt_plugins_3.3rc' The small round 'hp' logo button appears in the collection of icons in the lower right-hand corner of my desktop (next to the kmix speaker) automatically, which is nice, but nothing appears when I hover over it, and when I single or double left-click it, nothing happens. Doing a single right-click causes a list to appear, and I have to click on 'HP Device Manager', the toolbox stuff appears and functions correctly (with my HP Photosmart 3310 All-in-One connected via Ethernet). I'm not sure if this button behaviour is correct or not.
The resaon are insufficient access permissions: ----------------------------------------------------------------- root@host# ls -l /usr/lib/qt3/etc/settings/qt_plugins_3.3rc -rw-r----- 1 root root 745 May 15 16:39 /usr/lib/qt3/etc/settings/qt_plugins_3.3rc ----------------------------------------------------------------- I neither know the purpose of this file nor have I an idea what created this file because it is not owned by any RPM package. I filed a upstream question regarding this issue: https://answers.launchpad.net/hplip/+question/35112
The insufficient access permissions seem to be an old QT bug, see http://www.fedoraforum.org/forum/archive/index.php/t-134979.html and https://bugzilla.redhat.com/show_bug.cgi?id=189012
A question to the QT maintainers: It seems access permissions to /usr/lib/qt3/etc/settings/qt_plugins_3.3rc could change arbitrary by any Qt application which runs as root, see the URLs in comment #2 but is should be fixed but perhaps only in Red Hat's version of Qt? Is this a bug in Qt?
