** Attachment added: "USC.txt" https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1108612/+attachment/3505437/+files/USC.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to software-center in Ubuntu. https://bugs.launchpad.net/bugs/1108612 Title: side menu (List of Categories) displays links but no names Status in “software-center” package in Ubuntu: New Bug description: I use a CQ40 laptop with Ubuntu 12.10 installed. Software-center version: 5.4.1.3 The attached image shows a screenshot the software center(USC). You may notice that the list of categories on the left side is missing (One can find an empty box!). Even though it looks empty, when I hover the mouse pointer above it, it indicates the presence of hyperlinks. Those hyperlinks work, but one doesn't know which category it links to until you click the link. I tried changing the font, font size, it didn't work. When started through terminal, I got the following messages: :~$ 2013-01-29 12:37:56,792 - softwarecenter.ui.gtk3.app - INFO - setting up proxy 'None' 2013-01-29 12:37:56,828 - softwarecenter.db.database - INFO - open() database: path=None use_axi=True use_agent=True 2013-01-29 12:37:58,831 - softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file 2013-01-29 12:37:58,841 - softwarecenter.fixme - WARNING - logs to the root logger: '('/usr/lib/python2.7/dist-packages/gi/importer.py', 51, 'find_module')' 2013-01-29 12:37:58,841 - root - ERROR - Could not find any typelib for LaunchpadIntegration 2013-01-29 12:37:59,126 - softwarecenter.ui.gtk3.app - INFO - show_available_packages: search_text is '', app is None. 2013-01-29 12:37:59,688 - softwarecenter.db.pkginfo_impl.aptcache - INFO - aptcache.open() Please help.
