lrt test found crash file _usr_bin_unity8.32011.crash

crash file

This is different than the last one.

I am not sure if this is in mir or in unity8, the stack trace is not complete

This looks very similar to bug #1348702, fix committed in unity-scopes-api trunk.

Not sure that this is the same thing. bug #1348702 was quite clear-cut. This one, I don't recognise much at all.

A better stack trace would be useful. Any chance of getting that?

unfortunately there are issues with gdb on armhf, we won't be able to get a better stacktrace until after it's fixed. It doesn't look like it will be fixed very soon.

marking incomplete until we're able to get a stacktrace

I think this has been fixed, we can re-open it with a better bug from errors.ubuntu.com if it happens again. Marking invalid for now.

Marking invalid for lrt-crashes.
