SegFault if ~/VirtualBox/VDI folder is encfs encrypted folder.

Reported by: dammer Owned by:
Priority: major Component: virtual disk
Version: VirtualBox 2.0.0 Keywords: encfs, vdi
Cc: Guest type: Windows
Host type: Linux


System: Ubuntu 8.04 (i386)
encfs v 1.3.2

After upgrade from v 1.6 to 2.0, my old and newly created(2.0) guests don't work.

No any information about fault in log. When run VirtualBox from command prompt and try to run Guest OS i have only one message: Segfault. and return to console.

In version 1.6 VirtualBox all my Guest OS work fine.

Any chance to make a core dump available?

Ok, core dump created ( man CORE(5) say: /proc/sys/fs/suid_dumpable must be set to 1) Send dump to frank.

Got it, thanks, investigating. Added a note about SUID  to

Please could you attach the VBox.log file of such a session as well? Or does it crash that early that this file is not yet created?

And more: if I try to manually select the disc in the folder dialog ~/.VirtualBox/VDI folder is not displayed.
When I pointed out the name of the file manually sees his shell and displays the properties correctly. Maybe the problem in fuse mount? suid, uid, etc?
from /etc/mtab:

encfs /home/damir/.VirtualBox/VDI fuse.encfs rw,nosuid,nodev,default_permissions,user=damir 0 0

Sorry my English is googletranslated :)
