Public bug reported:
Binary package hint: wlassistant
System: Kubuntu 8.04
Kernel: 2.6.24-17-generic
Wireless Card Driver: Ralink rt2500
Package Version:
Qt: 3.3.8b
KDE: 3.5.9
Wireless Assistant: 0.5.7
After associating with a wireless network, if I move my laptop to any
place where the signal is too weak (i.e. the AP is hidden by some
obstacle), the application crashes as soon as the signal gets lost.
KCrash gives no information.
Extract from strace:
