Steven: Can't remember any, at least nothing recent. There might have
been some complaints with older versions, but can't really tell if it
was because of the share or queue. (And my irclogs don't show anything
useful...)

Title:
  App crashes on start with "big" (>3k files) downloads queue

Status in Linux DC++:
  Incomplete

Bug description:
  Detailed description of the issue:

  There is a problem with big downloads queue list handling.

  Now I'm trying to download around 2Gb (>3k) of photos from buddy with
  latest  LinuxDC++ version: 1.1.0~pre1~bzr (Ubuntu 10.10). After I've
  added a folder with all this files into queue, everything were fine,
  files were downloading and  ~/.dc++/Queue.xml is around 100Mb size.

  But when I closed app and then tried to re-open in, it utilized about
  100% CPU for 2-3 minutes and then crashed. After I've manually deleted
  ~/.dc++/Queue.xml and then restarted app and re-queued all files - it
  were working well, until next restart. So, it's just can't start with
  such a "huge" queue.

  Also I've noticed a periodical (every 5-10 seconds for 2-3 sec)
  overloads in moment with Queue.xml.tmp (around 39Mb) file
  creation/deletion:

  #top | grep linuxdcpp
  17851 ritsuka   21   1  658m 270m  14m S   41 13.5   1:51.36 linuxdcpp

  Of course, there is an easy solution for this case: do not add more
  than 1K files to queue at once. But isn't this limit too low? Maybe
  it's a bug?

  Steps to reproduce:
  - add a lot (>3k) of files to queue
  - close app
  - open app

  Expected results:
  Should handle it, probably? Or should not?

  Actual results:
  100% CPU for some time, than crashes.

  Version:
  tested on 1.1.0~pre1~bzr && 1.0.3

  OS:
  Ubuntu 10.10 Maverick x86_64 / 2.6.35-24-generic

  Hardware:
  Core 2 Duo 2.2GHz, 2Gb RAM

  Can provide my queue.xml list and/or any logs I have.
