[linux-audio-user] Audacity crashes

[Moeflon]

I have a problem with Audacity. 

When trying to master a mixed CD, audacity crashes if I have more than 5
tracks (mp3) open next to eachother. The problem starts (I think) when I
play a section of the last added track. The channel-synchronisation gets
out of sync, leaving me a soundoutput with a couple of miliseconds of
difference between the left and right channel. (Stereo-image seems much
wider) Than the sound starts breaking apart. (missed blocks I think) 

After a buggy playback, when I edit something, 9/10 audacity crashes.


This is the output I get:

Segmentation fault


I'm running Audacity 1.1.3.2. The problem arises both in 44100 &
48000-projects

Anybody experiencing similar problems?

Any sugestions what causes this?
