Description of Problem:

When using HTTPS in our application, after there has been some time of
inactivity (in most cases somewhere between 2-5 minutes, sometimes with the
device suspending, sometimes not (this time happend during profiling with
Instruments)), the app crashes in
Mono.Security.X509.OSX509Certificates.SecTrustCreateWithCertificates.

Steps to reproduce the problem:

We're using a mixture of System.Net.WebClient and UIWebViews, sometimes also
System.Net.HttpWebRequest, all with the same HTTPS url with a valid
certificate. No handling for invalid certificates is used.

Actual Results:

The app crashes.

Expected Results:

The HTTPS request should work.

How often does this happen? 

Often.
