The only thing that sort of stands out in valgrind is a number of calls to
windowState(), presumably from line 620 of
tqt3/src/styles/qcommonstyle.cpp

Can you try commenting out that line to see if it resolves the slow
startup issue?  You only need to recompile/reinstall TQt3 itself to test,
then log out/log back in to TDE.
