Package: hydrogen Version: 0.9.7-1+b1 Severity: important I get frequent segmentation faults when trying to create a new drumkit or modyfing parameters in current Debian stable Hydrogen. Adding/deleting sample layers seems to have a high probability of crashing. It could be a race condition when one thread tries to access a buffer that has been deleted by another thread. This is what I get when running under gdb:
Thread 7 "hydrogen" received signal SIGSEGV, Segmentation fault.
