The crash is in
255 int
256 virSecurityManagerTransactionStart(virSecurityManagerPtr mgr)
257 {
258 int ret = 0;
259
260 virObjectLock(mgr);
261 if (mgr->drv->transactionStart)
262 ret = mgr->drv->transactionStart(mgr);
263 virObjectUnlock(mgr);
264 return ret;
265 }
virObjectLock checks references before access.
But one can think of "mgr->drv" being a bad pointer and then the
mgr->drv->transactionStart being the crash.
