Adding new Torrents sometimes causes UI to freeze

[tekko]

I was tempted to try again with qBittorrent 3.1.0 alpha (26-12-2012) 

Same steps as before, torrent added constantly with new version.

GenericComrade and sledgehammer_999, nice team work.

Tests on my normal machine - Windows XP SP3 32 bit - Single Core - Pentium 4 2.8GHz:

Old Version Test (v3.0.6):
Uninstalled qBitTorrent (with "Remove configuration files" checked)
Ensured qBitTorrent Application Data and Local Application Data were gone.
Installed v3.0.6 (qbittorrent_3.0.6_setup.exe)
Added Torrent: Touhou album image collection v.15.torrent
Set "Save As" Path: C:\Temp\1\
Expanded Settings
Unchecked Start Torrent
Renamed base folder from "Touhou lossless music collection" to "Touhou"
Clicked OK
Killed qBittorrent after freezing for too long (it reached 4:00 CPU Time from 0:11)

Alpha Version Test (v3.1.0alpha 261212):
Uninstalled qBitTorrent (with "Remove configuration files" checked)
Ensured qBitTorrent Application Data and Local Application Data were gone.
Installed v3.1.0alpha 261212 (qbittorrent_3.1.0alpha_setup261212.exe), linked here: http://qbforums.shiki.hu/index.php?topi ... 71#msg5271
Added Torrent: Touhou album image collection v.15.torrent
Set "Save As" Path: C:\Temp\1\
Expanded Settings
Unchecked Start Torrent
Renamed base folder from "Touhou lossless music collection" to "Touhou"

QBitTorrent froze for ~19 Seconds of 100% CPU time (0:25->0:06)
Torrent appears on list successfully added.

More Success!

I've been using the Touhou torrent for my tests, but if there are other torrents you'd like for me to try, or any other steps, please let me know.

Thanks for your work on this problem, it is greatly appreciated!

Edit: Added my CPU specs to my previous posts.
