Gnome-disk-utility (palimpsest) crashes when trying to attach disk image
Last modified: 2012-06-03 19:29:50 EDT
Description of problem:
Any attempt to attach a disk image results in the program crashing.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Launch palimpsest
2. Click the PLUS button at bottom left corner of Disk Drives list.
3. Browse to and select an ISO image
4. Click Attach
Does not seem to matter if 'Set up read-only loop device' is checked. Running as regular user or with sudo does not change result.
If run from console you get the following output:
g_dbus_connection_real_closed: Remote peer vanished with error: Underlying GIOStream returned 0 bytes on an async read (g-io-error-quark, 0). Exiting.
Tried a few ISO images that work fine with an old fashioned mount -o loop
Try running it like this
$ G_DBUS_DEBUG=all palimpsest
and include the debug output. Thanks.

Here you are. Thank you!
Oh, let me guess - you are running in SELinux enforcing mode, right? try permissive ('setenforce 0' as root). Does that fix the problem?

selinux alert browser output
setenforce 0 does fix the problem.
Here is the selinux alert browser output.
Thanks, reassigning to selinux-policy.
Dan: there are two different cases when udisksd exchanges file descriptors with other peers (remember that these D-Bus messages, including the file descriptors, pass through the message bus daemon):
1. when attaching a disk image file - see comment 0 for how to reproduce. In this case the unprivileged user app (typically Disks) passes a file descriptor from a file he opened (could be from anywhere)
2. when creating/restoring disk images - in this case udisksd passes a file descriptor for the underlying block device (e.g. /dev/sdb or /dev/sdb1) to the unprivileged user app (typically Disks). To reproduce, simply find an unused USB stick or similar with an unused partition. Then click the gears in the under Volumes and a menu appears . Click "Create Disk Image"  and then "Start Creating..."
