Description

Certain combinations of symmetrical parts can trigger a Null Reference Exception crashing the game.

An example that is 100% repeatable on my system using the stock game is to use 2x or higher symmetry to radially connect several Cubic Octagonal Struts to a central part (doesn't matter what part), then also using symmetry try to connect a set of The Not-Rockomax Micronodes to those struts.

There are other combinations that are also 100% repeatable, but this is the most simple and smallest.

Attached is a log of the crash. I will post later with a video

History

#1 Updated by Ruedii over 11 years ago

Uploading the video file.

As a note, when the game crashes, the video jumps to the next open window which happens to be my terminal running the system monitor.

#2 Updated by Ruedii over 11 years ago

Another player tested it, and reported they got null-refrence exceptions when the VAB refused to attach the micronodes, but his system did not crash.

The issue has been tracked down to the fglrx Radeon video driver.

This issue causes many null reference exceptions to cause the game to crash.

I think addressing what is causing this behavior us more important than going around fixing every null reference exception.

Issue 506 experienced the same thing, and contains a .craft file with which a game crash can be forced with a bit of fiddling (.craft file uploaded here as well).

I got the game to crash with 0.21.1 when loading the .craft file in the VAB, selecting Mainsail, toggling symmetry to 6-fold by pressing 'x', then positioning the Mainsail onto the bottom of the fuel tanks so that it gets a green highlight and then toggling symmetry with 'x' a couple of times.

Crashing was pretty consistent for the original reporter of issue 506.

Note: This is dependent on bug #1182

#8 Updated by Ruedii about 11 years ago

Null Reference Exception still occures in 0.22

Does not hang as bad on systems not affected by bug #1182

Closing this report out for now. If you find it is still occuring in the latest version of KSP please open a new report (and this one can be linked to it.) For best results, the wiki contains really useful info for when creating a report http://bugs.kerbalspaceprogram.com/projects/ksp/wiki.
