OK, I also noticed that the timestamp on the PNG file is the same time
the commercial flagging finishes, and I confirmed this in the source

If you look at jobqueue.cpp you can see the preview being generated at
line 2091 (0.19 code, not SVN) AFTER commercial flagging has finished.

So, I guess when I delete a file that's being flagged it appears to the
backend the same as when flagging finished normally and it creates the

I'm guessing the most obvious solution is to move the thumbnail
generation so that it happens BEFORE commercial flagging and not AFTER.
This also seems to make more sense to me, as sometimes it can take
several hours to flag a program if there have been a lot of other
programs recorded at or around the same time.

Unfortunately I don't really have a suitable system setup to test any
changes I might make.
