System Information
Windows 10, i7 920, 48GB, GTX1080 6GB.

Blender Version
Broken: 2.79 official version with COA Tools add-on installed.
Worked: works in 2.78c and earlier.

Opening a linked library item works fine (select linked library item, and click "Edit Library: XXXX" button.
Making a change, and returning to the original master file crashes/closes Blender. No warning messages. It just closes.
When the master file is reloaded, the changes were saved.

Exact steps for others to reproduce the error
Install and activate the COA Tools add-on.
https://github.com/ndee85/coa_tools

Create a new Blender file, and link any object/group/etc. Save the file. Click the "Edit Library" button. The object opens fine. Edit the object. Click "Return to Original". Crash/Blender closes.

Please fix this. It is quite essential for a fluid linked library workflow.

Could not repro on macOS. Could you add crashlog?

No crash log is written. The "return to original" button does close the file correctly, but doesn't reload the original master file for some reason.

I get this error in the console:
Blender quit
Traceback (most recent call last):

File "C:\Program Files\Blender Foundation\Blender\2.79\scripts\addons\object_edit_linked.py", line 222, in draw
  text="Edit Library: %s" % context.active_object.dupli_group.name,

AttributeError: 'NoneType' object has no attribute 'name'

I assume you're using same instance rather than checked "open new instance" option?
What does console output say? (set debugging on)

Yes, same instance. With "open new instance" the original master blend file also closes after clicking the "update..." button.

This is what I get when I click "return to original file":

Can you still open both .blend files without using the addon ?

Herbert van der Wegen commented

2017-10-27 12:53:55 +02:00

Yes. And linking and reloading the library file using the outliner works as expected. It is just when I use the addon that Blender hits a snag.

@herbert123 judging from the last post do you run any other add-ons?
Can you attach the system-info.txt generated from the Help> Save System Info menu by dragging and dropping the whole .txt file into the comment field ( do not paste it's contents directly in the comment field it is difficult to read and breaks up the formatting).

For some further reading about how to attach files to reports check the link here:
https://wiki.blender.org/index.php/Dev:Doc/Process/Bug_Reports (under the Appending files to the report section)

It is possible that some other add-on running modal can interfere when trying to save or load blend files. The system info will give us information about the enabled add-ons.

I figured it out! COA Tools is the culprit. When that add-on is activated, Blender will crash.

I will report this bug on COA Tool's github as well.

Glad to hear that the source of the problem was found :)

Since the add-on issues are related to a third party one, for maintenance you'll have to contact the author, because COA tools not officially maintained / hosted by Blender - it's not in release nor contribution.

If there is some further issues with Edit Linked Library add-on, please feel free to post on this task so it can be reopened or create a new one.

Thanks, I posted a bug on the respective Github page. Still, it is odd that it works in previous versions (2.78 and 2.75), and stopped working in 2.79.
