Looks like problem with VirtualBox API.
Please clear kupfer cache (rm ~/.cache/kupfer/*) and check again.
Also please information about version of virtualbox.

I have already reinstalled Ubuntu 3 times since reporting this error. So unfortunately I cannot check what You ask. Nevertheless, I have not experienced this bug for long time now.

This still happens for me. After reading the chatter above, I cleared the .cache files, and for a day or so, kupfer seemed to work.

Today, it only lives for about 10s.

Here's an output log.

I have disabled VBox plugin, no difference.

Clearing the cache does indeed work, but after the cache is re-populated, kupfer starts crashing again.

why is this marked "incomplete"?
