And this is confusing. You're saying the project is up, you can use it, but 
everything is slow as molasses for several minutes? Here's what you should 
understand about those file operations... To the best of my knowledge we're 
talking KDE/Qt calls exclusively. They in turn make requests of the file 
system. The file system and associated daemons like fam then do their work 
returning the information to the KDE libraries which Quanta uses.

While it is hardly conclusive that the problem you're experincing is not 
caused by Quanta it is highly unlikely that Quanta is the cause. Even if only 
a few people actually complain, based on downloads of source going back to 
2001 and estimated growth of GNU/Linux use, I've estimated from several years 
back we probably had over a million users. Statistical probabilities develop 
with problem reports. Distribution configuration errors have historically 
been as much as 40%-60% of reported problems.

Given all that I would recommend contacting Kubuntu. If I can get indications  
of a particular factor I could dig in and look, but for instance something 
like a symlink is not generally looked at in most file management until you 
get to the file system or IO. If there is a problem with Kubuntu I hope they 
fix it. Hopefully you don't have to switch distributions to fix a bug, but 
I'd bet you would find this problem wasn't occuring elsewhere.
