Created attachment 47925 [details] Backtrace from hang point Version: 1.00 (using KDE 4.4.3) OS: Linux The configure dialogue hangs on launch making Kopete unusable. Backtrace suggests that it is waiting for v4l, which is used by (what I consider to be) a non essential component of the configuration. Reproducible: Always Steps to Reproduce: 1. Launch Kopete 2. Go to Configure dialogue Actual Results: Dialogue is drawn blank, and program becomes unresponsive and has to be terminated Expected Results: Configuration dialogue loads Notes: * I have two IVTV video cards * I have no webcams connected * The same setup worked in Fedora 11 just before I switched to Fedora 13 Packages: * kdenetwork-4.4.3-3.fc13.x86_64 * libv4l-0.7.91-1.fc13.x86_64 * kernel-2.6.33.5-112.fc13.x86_64
