Freeze when importing mp3 in 5.0.1

[alan*]

Freeze when importing mp3 in 5.0.1, it was like a 6 minute dance track, there was an awful lot of warp markers from the auto warp marking, waaay too many, there is no way that track could have that much variation ? So anyway, a lot of spinning colour wheel happening on and off like the machine was trying to work something out but couldn't, and then freeze, wouldn't play any clips, I seem to remember this happened in the beta as well. Program quit ok though, didn't crash.
