#679 NullPointerException and corrupted file

[Sandro Santilli]

SweetHome3D-5.2 on Ubuntu 14.04.
On saving a project (after having imported 3DModels-BlendSwap-CC-0-1.6.2.zip) I get this:

java.lang.NullPointerException

Trying to open the file again, results in:

I'm also attaching a screenshot of the display output right before the crash, in case it helps.

I tried again from a backup: importing the furniture library had nothing to do with the problem. Just opening a working file, importing the furniture, saving and exiting isn't enough to reproduce. I must have done something else, but don't know what :(

Still I shall note that even while it works, the NullPointerException is always printed on saving the project.

I would not know how to reproduce this anymore.
Feel free to close this report.

Sorry for the late anser.
Could you send me your file? Did it happen on some other files?

Anyway, I think I fixed this issue in April and the bug fix was released with version 5.3 yesterday.
