Crash in QHttpNetworkConnectionChannel::sendRequest

Client and Server are both Embedded Linux Kernel 2.6.37.6-4.0-20140320-S.
Client and Server communicate via HTTP
Client uses: QNetworkAccessManager::post()
Client and Server use SSL RSA
When Client has not received a reply from the server after a timeout, client calls QNetworkReply::abort() on the pending request

Client crashes randomly (from time to time after having run for a while) as follows:
