amarokcollectionscanner mmap()ing 6.3GB

[Hans Ecke]

Hi-

Attached is the tail end of a strace(1) trace for running 

   amarokcollectionscanner -r /music/mdb/music

It shows how it processes two files: "03 - 7' Instrumental.mp3" and "01 
- 7' Mix.mp3". When processing the latter file it mmap()s 3.3GB of RAM 
twice. The program stops at that point, till I kill it from another 
terminal.

Here are my stats:

   Linux 2.6.18
   2 cpu x86_64
   Fedora 5
   Qt 3.3.7
   KDE 3.5.5
   Amarok 1.4.4
   Taglib svn-20070123

I just updated taglib today because the current stable version 1.4 has 
problems with some id3v2 2.4 tags. And the newest amarok requires v2.4 
tags for correct utf-8 support. My music library has a lot of 
international tags.

How can I help fix this problem? How can I supply a more useful bug 
report?

Thanks!

Hans
