Please describe the problem:
Note: This occured in a 2.6.0 version of nautilus - I could not find a way to
indicate this, nor did I see anything in Bugzilla that relates.  If this has
been address, my apologies.

Issue:
When using CD Creator to burn a CD/DVD, the application hangs if there are files
with "bad Unicode" in their title.  This would not be a problem, except that no
error information is displayed, and hitting "Cancel" simply reports a cdrecord
error to the effect that the .iso file could not be read (well, ya... it never
was created because the thing hung! ;)  )

Diagnosis:
An attempt to create an iso separately (using "mkisofs -J -r -o ../myimage.iso
./*") revealed that the mkisofs fails when trying to make an image from a file
with "bad Unicode" - such as the funny combined AE character (called an "ash"?)
that appears in titles of things that are trying to be gothic.  Renaming the
offending files and rerunning CD Creator works.

It would be helpful to bomb out of CD Creator with the appropriate message(s)
passed on from the mkisofs (or equivalent) rather than hang.  It would be
stellar to find a way to present something useful like "Please rename file
'foo_with_a_funny_character.mp3' - it contains illegal characters".

:)

Steps to reproduce:
1. Add a file with a character not supported by Joliet extensions to CD Creator
2. Attempt to burn the CD


Actual results:
The "Writing CD Image" dialog appears, but the 'spinning CD' image stops, and no
progress bar appears.  Moving another window across the dialog eliminates the
image in the dialog's clipping context and the dialog is never redrawn.

Clicking "Cancel" apparently aborts the image creation, but still tries to write
the image, causing a separate error.

Expected results:
An error message stating that the file(s) need(s) to be renamed because the
name(s) contain invalid characters (a reference to the supported character
encoding would be helpful).  Naming the offending files by full path would be
most helpful.

Does this happen every time?
Yes.
