I tried installing all the packages that I wanted at once. Together with their dependencies, here are the packages I installed after installing Ubuntu 11.04 Beta1 and running an apt-get dist-upgrade:

I wasn't able to pinpoint which package exactly did it, so I decided to install the system again and installing the packages I wanted separately. Note that I tried uninstalling the above packages with apt-get remove --purge, but the bug did not go away. On my second reinstall, I did apt-get upgrade instead of apt-get dist- upgrade. Then I installed the packages separately. I show below each separate installation with the name of the package I wanted to install in the left-hand side and its dependencies (which were also installed) after the colon. * checkgmail: libcrypt-blowfish-perl libcrypt-simple-perl libcrypt-ssleay-perl libemail-mime-encodings-perl libgtk2-trayicon-perl libxml-namespacesupport-perl libxml-sax-expat-perl libxml-sax-perl libxml-simple-perl * ssh: openssh-server ssh-import-id * deluge-gtk: deluge-common libblas3gf libboost-filesystem1.42.0 libboost-python1.42.0 libboost-system1.42.0 libboost-thread1.42.0 libgfortran3 liblapack3gf libmikmod2 libportmidi0 libsdl-image1.2 libsdl-mixer1.2 libsdl-ttf2.0-0 libsmpeg0 libtorrent-rasterbar6 python-libtorrent python-numpy python-pygame * libreoffice-l10n-pt-br * libreoffice-l10n-it * language-support-pt: language-support-writing-pt myspell-pt myspell-pt-br myspell-pt-pt wbrazilian wportuguese * language-support-it: language-support-writing-it myspell-it witalian * hyphen-it * texlive: lacheck latex-beamer latex-xcolor lmodern luatex pgf prosper ps2eps tex-common texlive-base texlive-binaries texlive-common texlive-doc-base texlive-extra-utils texlive-font-utils texlive-fonts-recommended texlive-fonts-recommended-doc texlive-generic-recommended texlive-latex-base texlive-latex-base-doc texlive-latex-recommended texlive-latex-recommended-doc texlive-luatex texlive-pstricks texlive-pstricks-doc tipa * texmaker: appmenu-qt asymptote asymptote-doc blt freeglut3 imagemagick libaudio2 libcdt4 libdbusmenu-qt2 libgc1c2 libgraph4 libgvc5 libilmbase6 liblqr-1-0 libmagickcore3 libmagickcore3-extra libmagickwand3 libmng1 libnetpbm10 libopenexr6 libpathplan4 libphonon4 libpoppler-qt4-3 libqt4-dbus libqt4-network libqt4-opengl libqt4-xml libqtcore4 libqtgui4 libqtwebkit4 libsigsegv0 netpbm phonon phonon-backend-gstreamer preview-latex-style psutils python-imaging-tk python-tk tcl8.5 texlive-latex-extra texlive-latex-extra-doc texlive-pictures texlive-pictures-doc texmaker-data tk8.5 * gimp: gimp-data libbabl-0.0-0 libgegl-0.0-0 libgimp2.0 * lame: libmp3lame0 * smplayer: esound-common libaudiofile0 libbluray0 libesd0 liblzo2-2 libopenal1 libsvga1 libvdpau1 libx264-106 libxvidcore4 mplayer smplayer-themes smplayer-translations * easytag-aac: libmp4v2-0 * picard: libdiscid0 libmysqlclient16 libqt4-declarative libqt4-designer libqt4-help libqt4-script libqt4-scripttools libqt4-sql libqt4-sql-mysql libqt4-svg libqt4-test libqt4-xmlpatterns libqtassistantclient4 mysql-common python-mutagen python-qt4 python-sip * bluefish: bluefish-data bluefish-plugins * openjdk-6-jdk: libice-dev libpthread-stubs0 libpthread-stubs0-dev libsm-dev libx11-dev libxau-dev libxcb1-dev libxdmcp-dev libxt-dev x11proto-core-dev x11proto-input-dev x11proto-kb-dev xtrans-dev * revelation: cracklib-runtime gnome-extra-icons libcrack2 python-gnomeapplet * rar * unrar-free * cpulimit * mysql-server: libdbd-mysql-perl libdbi-perl libhtml-template-perl libnet-daemon-perl libplrpc-perl mysql-client-5.1 mysql-client-core-5.1 mysql-server-5.1 mysql-server-core-5.1 * mysql-client * mysql-admin: mysql-gui-tools-common mysql-query-browser * wine1.0: cabextract ttf-mscorefonts-installer winbind wine1.0-gecko * ttf-xfree86-nonfree * compizconfig-settings-manager: python-compizconfig * mencoder * ffmpeg: libavdevice52 libavfilter1 * x264 * faac: libfaac0 * sound-juicer: gstreamer0.10-lame gstreamer0.10-plugins-really-bad * chromium-browser: chromium-browser-inspector chromium-browser-l10n chromium-codecs-ffmpeg In this way, the bug *did not* manifest. However, I can't explain why. If I had the time, I'd try installing, dist-upgrading and apt-getting all packages at once to confirm that the bug is reproduceable. Unfortunately I don't have the time. So I'll go ahead and mark the bug as invalid, as it's not affecting me any longer.
