Rarely crushing application when deleting widget

[nedlab]

I have a widget, that aggregate QTimer and QHttp objects. On timer's event there is some data exchange.
Problem in that at asynchronous removal the widget, application takes off. There is it seldom enough. I tried to cause methods QTimer::stop(), QHttp::abort() before removal - does not help.
How must I correctly delete my widget?:confused:

without code: just guesswork
try deleteLater() instead
