After analysis, this should be related to the timing of adding a new entry when there is file create. When taking a picture, gecko will new a file first. At this time, we got file create event. Mtp add a entry for this file. (not a complete file) Then camera will modify this file to complete a picture. As discussed with Eden, he will add code for "file modified event" and update the database accordingly.

Then Camera app finished the file editing at line 4848, and send event to fileWatcher, but MozMtpServer ignored this event. I add some "modified" event handle for MozMtpServer. Since MtpServer does not support "modified" notification directly, we support it as removing original entry and re-adding the entry in MozMtpDatabase.
Comment on attachment 8500251 [details] [diff] [review] Handle "modified" event for MozMtpDatabase in FileWatcherUpdate(). This bug is similar with bug 1074604. I integrate the solution and continue related discussion to bug 1074604.

Yes, I think it is the same reason. I will make it dup with bug 1074604.
