example of freezed app and KCategorizedView
Version: SVN (using Devel)
When a KCategorizedView is used in an aplication window and that has a scrollbar due too many items, wholle app will freeze.
Steps to Reproduce:
For e.g. plasma-desktop from 4.5beta1:
- lock widgets
- right click on system tray
- select system tray settings entry from menu
- if not, select display section. If that category has a scrollbar, plasma-dekstop will freeze
- click menu: tools -> script manager
- if you have many scripts that will require scrollbar to list them, amarok will freeze
Both aplications were tested on stable 4.4.4 and upcoming 4.5beta1. Amarok is from git. Problem is desktop-wide.
I can confirm this also happens with plasma tray settings, which also implements KCategorizedView.
