Really strange problem with evince PDF reader and .mutt directory

[Chris Green]

I have a very strange error when trying to use evince to read PDF files.

If (and only if) the PDF file is somewhere in my .mutt directory then
evince fails with a "Permission Denied" screen.  It's definitely
something to do with the name ".mutt" as simply changing the same
makes evince work.

So, I have moved my real .mutt directory out of the way and have just
the following:-

    chris at t470$ ls -al .mitt
    total 2788
    drwxrwxr-x  2 chris chris    4096 Oct 19 19:11 .
    drwxr-xr-x 63 chris chris    4096 Oct 19 19:11 ..
    -rw-------  1 chris chris 2845720 Oct 19 19:11 fred.pdf
    chris at t470$ ls -al .mutt
    total 2788
    drwxrwxr-x  2 chris chris    4096 Oct 19 19:12 .
    drwxr-xr-x 63 chris chris    4096 Oct 19 19:11 ..
    -rw-------  1 chris chris 2845720 Oct 19 19:12 fred.pdf
    chris at t470$ 

Running 'evince ~/.mitt/fred.pdf' displays the PDF file successfully
but running 'evince ~/.mutt/fred.pdf' produces a Permission Denied
message in a pop-up window.  All directory names I have tried other
than .mutt allow the PDF file to be read.

Has anyone else here seen anything like this?  It would seem that it's
an error in evince but of some relevance to mutt use.
