[ubuntu] Kile TeX editor freezes on open file

view story

http://ubuntuforums.org – When I try to use Kile's open file dialog (File->Open, ctrl+o, or the open icon), a blank window with the title "Open Files - Kile" appears and hangs. I have to kill or end the Kile process. The only way I can open files in Kile is to drag and drop from a Nautilus directory browser. It is very annoying because I sometimes forget and have to start Kile again. I am using Ubuntu 11.10 and Kile 2.1. I have tried renaming my Kile config file (~/.kde/share/config/kilerc) and starting from scratch, but that didn't work. I'd appreciate any help. Kevin (Hardware)
