Loss of .xmp edit information
I have experienced a few losses of image edits.
It really sux when you spend hours editing 100s of shots from a shoot, then come back and they are gone.
I think there are probably two causes of this:
(1) permissions (user does not have write access to image dir to write .xmp files)
(2) disk space issues (no free space left on device)
Some checks for the above issues or on the handling in these cases should definitely be performed to prevent others.
I have since upgraded to the latest git stable so am not able to retest. However, this really sucks and should be looked at if not yet fixed :)
