You can run startkde like:
  strace -tt -o /tmp/profiledir -f -ff startkde

That will strace all processes started from startkde with timestamps

It has two big disadvantages:
1. strace makes all the syscalls slower
2. it's a pain to sort out which process is what and who is doing what when

Would be nice to have a GUI tool that could analyze such a set of straces and 
plot the activity for each process on a timeline

Cheers,
Waldo
