[Pkg-ime-devel] Bug#862814: ibus-ui (systray icon) mis-detects Qt/KDE version

[Ralf Jung]

Package: ibus
Version: 1.5.14-2
Severity: normal

Dear Maintainer,

Swithcing to the table-latex input method, the panel prints the following warning on the console:

(ibus-ui-gtk3:28333): IBUS-WARNING **: plasma-workspace 5.2 or later is required to show the absolute path icon /usr/share/ibus-table/icons/latex.svg. Currently check qtbase 5.4 since there is no way to check the version of plasma-workspace.

This explains why the UI deos not display the correct icon in the panel.
This warning originates from the following code in panel.vala:

#if INDICATOR_ENGINE_ICON
                m_indicator.set_icon_full(icon_name, "");
#else
                warning("plasma-workspace 5.2 or later is required to " +
                        "show the absolute path icon %s. Currently check " +
                        "qtbase 5.4 since there is no way to check " +
                        "the version of plasma-workspace.", icon_name);
                m_indicator.set_icon_full("ibus-engine", "");
#endif

Debian stretch is on Qt 5.4 and plasma-workspace 5.2 since at least two years.
It seems that during the build process, the wrong version is detected, and hence ibus-ui doesn't even try to show the correct icon.

The package should probably be modified such that INDICATOR_ENGINE_ICON is always set.

Kind regards,
Ralf
