Clicking the file chooser button crashes VirtualBox on Zesty

[Jeremy Bícha]

What Happens
============

If I click any of the file chooser buttons, VirtualBox crashes.
Perhaps the fastest way to test this is to click File>Import Applicance. Then click the yellow folder button to browse for a file.

I submitted this to errors.ubuntu.com but maybe it's not been processed yet.

Hello, can't reproduce:
1) created zesty clean vm
2) installed vbox 5.1.14 inside it
3) installed ext-pack and added my user to vboxusers
4) touch foo.ova
5) try to import appliance foo.ova

Result: VERR_TAR_UNEXPECTED_EOS, but no crash

also exporting a debian netinst and reimporting it works

Hmm, I still experience this bug with 5.1.14-dfsg-1ubuntu1

My host system is Ubuntu GNOME zesty amd64.

Sorry, I didn't see your response until today.

[Gianfranco Costamagna (costamagnagianfranco)]

Interesting, I don't have this bug with zesty on a virtualbox environment...
I can't install gnome, because I can't make it start correctly, do you experience this with Unity aswell?

[Expired for virtualbox (Ubuntu) because there has been no activity for 60 days.]

Turns out this only happens when I use Wayland (as in GNOME on Wayland). Sorry I didn't realize that before today.
