Package: qt5ct
Version: 0.37-1
Severity: normal

Dear maintainers,

On my system I have several large icon themes installed (Numix-Circle,
Moka, Papirus, ...), and this causes qt5ct to start up very slowly.

Running qt5ct in gdb and breaking during the delay consistently points
to IconThemePage::findIcon being called a lot.
