[issue] can't use alt icons from delta icon pack

[ridolagunju]

as the title says i can't set any alt icons from the delta icon pack on pie launcher.

i checked and it seems like it's all alt icons not just the ones i tried.

edit: i looked through the closed issues and found an issue had been closed about a similar bug, #163 said to have been fixed in version 1.23.6 but the issue still persists in version 1.23.8.
