KMix crashes a few minutes after I log in. I do get a sound driver error the startup, but I can't find any logs on the error thats useful. I also I can't think of a way to replicate the problem, what maybe worth mentioning is that I am using a "AMD Athlon(tm) 64 X2 Dual Core Processor 4000+" (according to dmesg), but are running Kubuntu 8.10 32bit with the "Linux version 2.6.27-9-generic" kernel. Here are the backtrace output from the KDE Crash Handler. Hope this is helpful.

Application: KMix (kmix), signal SIGABRT
