Often it seems that whenever I try to preview presets (clicking on the .xpf file) for the LB302 instrument plugin, lmms crashes, giving a segmentation fault. Previewing presets/samples from the other instrument plugins seems fine. I am using Ubuntu 14.10 and lmms 1.0.95 that was built from source. I made an output using gdb including a full backtrace:
