Thanks!

I noticed that, on my Debian system, the user interface was not
displaying any icons.

I fixed it for myself by making the package use the 'qt-wrap' phase from
the Qt build system fixed this, which adds a wrapper for the
XDG_DATA_DIRS, XDG_CONFIG_DIRS, QT_PLUGIN_PATH, and QML2_IMPORT_PATH
environment variables.

I've attached a patch that does this. Can you check that it still works
for you?
