[Bug 1304004] Re: transmission-gtk crashed with SIGSEGV in gnutls_x509_crt_import()

 

I have no simple reproducer, the only one really working here is:

* Setup Ubuntu Trusty machine (mine is a i386 guest, but amd64 should have same bug)
* Install Zabbix Monitoring system
* "Configuration->Hosts": Create host "test"
* "Configuration->Hosts:" Click on "Applications" in host "test", create application "test"
* "Configuration->Hosts:" Click on "web" in host "test", add a web scenario. Create a test step for e.g. https://www.google.at/
Run the test and see if latest data contains, e.g. response time measurements for google.

When OK, add an /etc/hosts entry for "www.google.at" to point to an
Apache 2.4 server with SSL/SNI. (I can supply you with an IP off-list).

Afterwards "tail -f /var/log/syslog" should show you zabbix server crash
reports every some seconds.
