LinuxSampler crashes Ardour3 at session load. I've confirmed with the Ardour-devs that this is indeed a LinuxSampler-issue. I have also confirmed that some others have the same issue. Eventually it works, after trying to load the session ~5 times. I'm using latest svn of LinuxSampler and Ardour3. It's a session with several (~5) LinuxSampler lv2-plugins loaded. Here's a backtrace from Ardour3-dbg: [New Thread 0x7fffc0367700 (LWP 6427)] [Thread 0x7fffc3066700 (LWP 6426) exited] Loading LV2 state from /home/zth/PARTYLIMER/plugins/159133/state1/state.ttl [Thread 0x7fffc0367700 (LWP 6427) exited] [New Thread 0x7fffc3066700 (LWP 6428)] Stopping disk thread...OK [Thread 0x7fffc3066700 (LWP 6428) exited] Starting disk thread...[New Thread 0x7fffc3066700 (LWP 6429)] OK EQ support: no [Thread 0x7fffc3066700 (LWP 6429) exited] [New Thread 0x7fffc0367700 (LWP 6430)] Scheduling '/home/zth/SAMPLES/Instruments/SalamanderGrandPianoV2_48khz24bit/SalamanderGrandPianoV2.sfz' (Index=0) to be loaded in background (if not loaded yet).
