Crash during scan

[greatidea311]

I've been able to scan fine previously but app is crashing sometime during the scan. I'm got a number of files across many locations so it takes a while and is difficult to know at what point it crashes exactly. I will selectively disable some of the locations to see if that fixes the issue, but it's very time consuming.

From the log, this is the entry for the scan, followed by a list of the file locations.

Scanning
- Video mode: Match thumbnails
- All file types
- Ignore zero size files

Event viewer does have a .NET runtime error associated with the crash:

I see the 'access violation' exception message, but there are not any permission settings that would cause this. This is the second event that comes immediately after the first:

It looks like the external MediaInfo library has crashed on a particular file, taking DC down with it.
Unfortunately with this type of crash the .NET framework doesn't allow the program to continue. I'm currently looking at how to get it to log the last file read before the crash to help with this type of problem.

The only thing you can do currently is to narrow down the search. You can also run in Regular Mode to find exact duplicates only - this doesn't read the video metadata so will not trigger the crash.
