Occassional NullReferenceException Error

[z06racer66]

I've noticed this for awhile now even with previous versions but could never track the reason down, but on occasion after watching a video I will get a NullReferenceException error when I press the escape key to go back to the main list of movies. I'm currently running nPVR 2.4.3 with patches through #7. Attached is the exception window text. There was nothing in the log files that I could see but I can upload those as well if anyone thinks that would help. Any thoughts on what is happening?

Thanks.

I'm away from home for a couple of weeks, and only have an iPad with me, so unfortunately can't open attachments. Can you post the body of that file?

I've been resetting my channel information and had a System.NullReferenceException crash today. I'm operating NextPVR 3.6.6. The error dump is:

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
