bash's sort is not complying

I have a file listing all the files on a drive.
The format of the file is:
NumberOfSlashes:FileName:FileSize:FilePath

I got NumberOfSlashes c/o awk.
I want numeric sort on the first column, and general sort on the 4th.


Trying:
cat thefile.txt | sort -t : -k 1,1n -k 4,4

What I get is:
1:  Job Search:135316:/Deskop, Iomega's, Jan 2014
1: Essentials, 2nd Release:59216:/Deskop, Iomega's, Jan 2014
1: PRINTME alias:1941900:/Deskop, Iomega's, Jan 2014
1: Specials alias:519032:/Deskop, Iomega's, Jan 2014
1:.0 Specials alias:519032:/Deskop, Iomega's, Jan 2014
1:.0.localized:0:/Deskop, Iomega's, Jan 2014

As you can see, it's sorting on col 2 for the 2nd criteria, not the 4th.
For -t I've used all of these, no diff.  -t ":"     -t :     -t \:

I did this testing before I looked on the web, and this SHOULD work.
But it doesn't.
==================

I also tried:
cat thefile.txt | sort -t : -k 1,1n -k 4,4d

But even after I changed LC_ALL='C', like it asked, it seems to be eliminating "/" and "-" and who knows what else.  The error message on this is:

sort: string comparison failed: Illegal byte sequence
sort: Set LC_ALL='C' to work around the problem.
sort: The strings compared were `LibraryMailV2AosIMAPrsmithbothellmailmboxDraftsmbox' and `LibraryMailV2AosIMAPrsmithbothellmailmboxExchange \306mbox'.

Never the less, I'm not getting the sort I want.

Any ideas?

It looks to me like
1:  Job Search:135316:/Deskop, Iomega's, Jan 2014
1: Essentials, 2nd Release:59216:/Deskop, Iomega's, Jan 2014
1: PRINTME alias:1941900:/Deskop, Iomega's, Jan 2014
1: Specials alias:519032:/Deskop, Iomega's, Jan 2014
1:.0 Specials alias:519032:/Deskop, Iomega's, Jan 2014
1:.0.localized:0:/Deskop, Iomega's, Jan 2014
Are identical in the 1st and 4th columns, so how can you say it is not sorted by them?

This sample output has "/Deskop, Iomega's, Jan 2014" as its first row, supposedly sorted, but I have files at the root, "/", and a DIR or two that start with a space.  They should be at top.  There are a few hundred thousand files in the listing.
Is my `sort` just misbehaving?
I'll look to see if anyone else has mentioned this.

The sort command seems to be working for me on sample input I've tried.
Can you show a sample that demonstrates unsorted 1st or 4th columns, along with the same rows in the order that you would have wanted them in?
If we don't have a way to get `sort` to work for you, would doing it with another command be satisfactory?

Hi ozo,
Turns out it was my mistake.  When I returned to the problem, before my post, I was sourcing the wrong file, one that I had removed those "missing" files.  
Sort is the working good.
My apologies for wasting your time.
