            Bug ID: 350186
           Summary: K3b hangs when burning iso image without read
                    permissions.
           Product: k3b
           Version: 2.0.3
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: GUI/Usability
          Assignee: k3b at kde.org

K3b hangs indefinitely at stage Starting SAO writing at 10x speed wiht both
progress indicators showing 0% when burning an iso image you do not have read
permission for. 

Note that burning the same image works using exactly same procedure if you have
read permission to the image.


Reproducible: Always

Steps to Reproduce:
1. Make sure you do not have read permissions for an iso image:
$chmod a-r image.iso

2. Open k3b.
3. Select "Burn Image"
4. Note that k3b reports "Seems not to be useable image"
5. Set Image type to correct one (Plain data image).
6. Click "Start".


Actual Results:  
K3b hangs indefinitely. 

Expected Results:  
Failure to burn the disk and report that it is unable to read file image.iso.

Alternatively:
Instead of reporting "Seems not to be useable image" report "Unable to read
file" and not let user to proceed to actual burning stage.
