Well, I try to fix crashes, but the age of my computer is... painfully 
apparent.  gdb here is nearly unusable (speedwise).  I appreciate your 
efforts, but often enough merely a backtrace is not enough.

And yes you can expect more patches to noatun before the release.

Must be a Qt bug.  You'd be able to more easily get my attention by using

I commited that, arts has no maintainer.  The bitrot has begun.

And a feature that crashes my machine is one that will be not shipped; because 
I will inevitably be held to blame for if it fails for someone else, and you 
try to tell a user "yeah, it crashes here too, see how competent we are?" ...

I don't believe you.  Be aware the slider is logarithmic.  You won't easily be 
able to hear the effect unless you raise the level isntead of lowering it.  
This is something I have in store for kde 3.2, with a major Eq overhaul, 
implmenting some really cool stuff.

My peak is a mere 14kHz in fact, and I'm merely 18.  I suspect it's more to do 
with genes and less to due with age.  Although I guess going to rock concerts 
doesn't help either ;)

That's because it's a useless feature, hence never implemented.

Or not one useful enough to warrant my adding it, and its cpu usage.

Arts has no maintainer now, AFAIK.  Shame, isn't it.  What's necessary is for 
their mcopclass file to be appropriately changed so they don't fall into the 
noatun filter.  Patches accepted.

>   I'm a very big fan of the computer multimedia, especially sound

I just like music, so I wrote a media player.  Except getting whiny emails 
from users who don't like the software they're getting for free because of a 
bug that's not in my code doesn't exactly motivate me, and the complaining of 
certain developers due to certain design decisions that I made in the 
software I wrote over the course of two and a half years also doesn't exactly 
float my boat.  I don't exactly see Alan Cox waving a banner with a certain 
multi-pronged eating utensil in front of Linus Torvalds.

Noatun never crashes for me, that's all that counts, as far as I'm concerned.
