#192 Multitrack Seg Fault

[Doug Webb]

In Multitrack Mode after dropping a clip or audio into a track I get a SEG FAULT. I just did a fresh install of Ubuntu 13.04 AMD64 because I never did get lives working under Ubuntu 12 with the same problem I assumed was a local configuration error.

Here's a backtrace:

You will need to get a longer backtrace - press return a few times after backtrace.

Is this still a problem or can I close it now ?
