Unity crashes when saving something while being out of space
To reproduce:
1) Have an almost full partition (I used a USB Drive for testing)
2) Create a project there
3) Finish filling up the partition so that it would be completely full (<2-4 mb of free space)
4) Duplicate an asset with CTRL + D so that you would go over the limit
Expected: Either Unity stops you from duplicating or informatively tells the problem while crashing
Actual: It just crashes with "data offset != file.GetPosition()", which doesn't make the problem clear

Resolution Note:
There is no catch-all solution to this problem and certainly none that can be applied whilst being certain not to reduce stability. The existing solution of warning the user regarding low disk space at load time is sufficient.
