Hi I experience something strange: gsequencer: ../nptl/pthread_mutex_lock.c:349: __pthread_mutex_lock_full: Assertion `INTERNAL_SYSCALL_ERRNO (e, __err) != EDEADLK || (kind != PTHREAD_MUTEX_ERRORCHECK_NP && kind != PTHREAD_MUTEX_RECURSIVE_NP)' failed. Aborted The window on XOrg is still present but the process doesn't exist anymore. Cheers, Joël
