 Perhaps you should have. Here, after stripping, it's about 6,35M vs 5,9M lib 
sizes. However, you forgot one thing: Qt's plugin system isn't very smart and 
loads plugins at the first opportunity. So in fact, you just managed to 
increase both memory usage and startup time, congratulations >;).

 Just try it, I have here an app which just creates KApplication and call 
app.exec() . KApplication creation time is about 0,12s vs 0,13s (no plugins 
vs plugins), I admit these are no precise numbers, but dlopening will 
definitely take longer than just having it as part of the lib. You can check 
the plugins are loaded by simply attaching gdb to this running process and 
watching gdb listing libs it's reading the info from.

 Unless you have more arguments for it, I'll remove the flag from the 
suggested ones.
