Conduct a search or test -f over a path with spaces

I am organizing my music library on a NAS server. I want to print a list of all the directories that are missing the cover art (at least one or more jpeg file). I have successfully created a file with each line containing the path to each occurance of one or more .mp3 files. That path is also expected to have one or more files ending in .jpg or .JPG.

My input file strings look like this:
Code:
/c/mp3/Bad Company/Rough Diamonds
/c/mp3/Bad Company/Burnin' Sky

Most of the directory paths have one or more spaces in the directory, preventing me from testing for files with the .jpg extension, plus I have no idea how to do a case-intensive test. I will probably just have to perform two tests. I get a file not found error if I quote the entire string like:
Code:
"/c/mp3/Bad Company/Rough Diamonds"

After much searching, I decided I need to convert each path to this format"
Code:
/c/mp3/"Bad Company"/"Rough Diamonds"

If I can just get the path in the above format, I should be able to test for a jpg file with:
Code:
[ -f /c/mp3/"Bad Company"/"Rough Diamonds"/*.jpg" ]

I have tried using the IFS="/" with the bash read and also awk with the IFS="/". Both these methods continue to use the space (and /) as an IFS and I end up with 6 fields in the case with the above path.

I am running an old version of linux, 2.6.17.14ReadyNAS, but I could do this over nfs with a modern kernel and tools. Any help would be greatly appreciated.

KLDCONFIG(8)						    BSD System Manager's Manual 					      KLDCONFIG(8)

NAME
kldconfig -- display or modify the kernel module search path SYNOPSIS
kldconfig [-dfimnUv] [-S sysctlname] [path ...] kldconfig -r DESCRIPTION
The kldconfig utility displays or modifies the search path used by the kernel when loading modules using the kldload(8) utility or the kldload(2) syscall. The following options are available: -d Remove the specified paths from the module search path. -f Do not display a diagnostic message if a path specified for adding is already present in the search path, or if a path specified for removing is not present in the search path. This may be useful in startup/shutdown scripts for adding a path to a file system which is still not mounted, or in shutdown scripts for unconditionally removing a path that may have been added during startup. -i Add the specified paths to the beginning of the search path, not to the end. This option can only be used when adding paths. -m Instead of replacing the module search path with the set of paths specified, ``merge'' in the new entries. -n Do not actually change the module search path. -r Display the current search path. This option cannot be used if any paths are also specified. -S sysctlname Specify the sysctl name to use instead of the default kern.module_path. -U ``Unique-ify'' the current search path - if any of the directories is repeated one or more times, only the first occurrence remains. This option implies -m. -v Verbose output: display the new module search path. If the path has been changed, and the -v flag is specified more than once, the old path is displayed as well. FILES
/boot/kernel, /boot/modules, /modules The default module search path used by the kernel. EXIT STATUS
The kldconfig utility exits 0 on success, and >0 if an error occurs. SEE ALSO
kldload(2), kldload(8), sysctl(8) HISTORY
The kldconfig utility first appeared in FreeBSD 4.4. AUTHORS
