** Description changed: + [ Impact ] + + * A change in Qt resulted in lxqt-config's Appearance -> Icons Theme + view showing no icon themes. A blank list is shown instead, which is + confusing and a regression from 26.04. + + * lxqt-config 2.4.0 (the version in 26.10) already has a fix, but this + fix is enabled at build time, and only enables itself when building + against Qt 6.11. The last build of lxqt-config most likely happened + before Qt 6.11 was uploaded. A no-change rebuild is sufficient to fix + the issue. + + [ Test Plan ] + + * On a Lubuntu 26.10 system, install the updated lxqt-config package from stonking-proposed. + * Click on the Application Menu > LXQt Settings > Appearance. + * Click the Icons Theme item in the sidebar. + * Confirm icon themes appear. + * Confirm one can switch between icon themes successfully. + * Confirm other basic features of lxqt-config function as expected. + + [ Where problems could occur ] + + * Any bugs introduced by code that is conditionally enabled when + compiled against Qt 6.11 may be introduced when this is done. At the + moment, the fix for the icons theme bug is the only such code in lxqt- + config (see https://github.com/lxqt/lxqt- + config/blob/20661be212e0dcd513ffa5d01717f73ed51d8ca0/lxqt-config- + appearance/iconthemeinfo.cpp#L53), so the above test plan should be + sufficient to catch such issues. + + ----- + + Original bug report: + On Lubuntu 26.10 (Stonking Stingray), the icon theme selection list in lxqt-config-appearance is completely empty, even though icon themes are installed in /usr/share/icons/. lxqt-config 2.4.0-0ubuntu1 includes the upstream code fix for the Qt 6.11 strict parsing issue (issue #1188), but the package was built on 2026-04-30 against Qt 6.10. Stonking subsequently ships Qt 6.11.2, so the binary needs to be recompiled against Qt 6.11 for the fix to take effect. Upstream confirmation: - Issue: https://github.com/lxqt/lxqt-config/issues/1188 - Maintainer (tsujan, Oct 19 2026): "If Qt >= 6.11 has come to your distro - recently, lxqt-config needs to be recompiled against it." + recently, lxqt-config needs to be recompiled against it." - 2.3.2 release notes: "Fixed too strict parsing of icon themes with Qt6.11, - which caused an empty icon themes pane in lxqt-appearance." + which caused an empty icon themes pane in lxqt-appearance." Steps to reproduce: 1. Open LXQt Configuration Center → Appearance → Icons Theme 2. The list is empty despite icon themes being installed. System info: - Lubuntu 26.10 (Stonking Stingray) - lxqt-config: 2.4.0-0ubuntu1 - Qt: 6.11.2
