issue (bug_risk): Guard against DConfig::create() returning nullptr before dereferencing config.

If DConfig::create() returns nullptr, config->value(...) will dereference a null pointer and crash. Please check config before use and either treat a null config as "no safe commands" (deny all) or fall back to a reasonable default.


if (!safeCommands.contains(cmd)) {
qWarning(notifyLog) << "The command is not allowed to be executed:" << cmd << safeCommands;
return;
}

pro.setProgram(cmd);
pro.setArguments(args);
