3.1.7 (2826) Show manager/File browser crash

3.1.7

H3
Two external screens
USB keyboard
DP8000

I had quite a total crash today also.
After running the show I was making a backup. I just pressed backup, typed the file name and after pressing enter the console crashed.
Screens went blank, only X pointer left. Console responded to PIG+OPEN+BACKSPACE and all processes showed not responding. I pressed OK on screen (trackball/pointer was not responding). After that I was not able to get processes window back.
Only option was to use main switch and wait the battery die.
After restart I made a new backup which was successful.
The console managed to make a backup file when it crashed, but had no time to check what there was in the file. I overwrote it.
