I was debugging TSM_StringConverter and found an oddity. If the saved variables are wiped, or the addon is freshly installed, the GUI and chat messages are not displayed. If I /reload my UI and don't change any of settings, the slash commands work.

Further, the slash commands do not work at all during a fresh installation. It is like they aren't being initialized when they are called. The test prints in PEW are not doing anything during the first install either. They work after a /reload.

And I don't know why I am getting this behaviour.

local title, addon = ...
local L = addon.L
local gui = LibStub("AceGUI-3.0")

local text_store = "" -- store the edit box text
local main_frame

addon.frame = CreateFrame("Frame")
addon.frame:RegisterEvent("PLAYER_LOGIN")
addon.frame:RegisterEvent("PLAYER_ENTERING_WORLD")
addon.frame:SetScript("OnEvent", function(self, event, ...)
    addon[event](self, ...)
end)

local function PrintCommands()
    print(L["/tsmsc slash commands:"])
    print("  " .. HELP_LABEL:lower() .. " " .. L["or ? prints this menu."])
    print("  " .. L["login toggles showing the frame when you first log into WoW."])
    print("  " .. L["reload toggles showing the frame when you reload your UI."])
    print("  " .. L["message toggles displaying this message when you log into WoW."])
    print("  " .. L["Any other entry toggles the frame"])
    print(L["Example: /tsmsc login"])
end

local function ToggleFrame()
    if main_frame and main_frame:IsShown() then return end

    main_frame = main_frame or gui:Create("Frame")
    main_frame:SetTitle(L["TSM String Converter"])
    main_frame:SetStatusText(L["TradeSkillMaster itemID String Fixer"])
    main_frame:SetCallback("OnClose", function(widget)
        text_store = ""

        -- break text_store entirely, and fix it (credit to krowbar71 on the Wowinterface forums)
