[bug-gv] zoom problem with pdf-files

[Joerg van den Hoff]

hi there,

I'd like to report the following problem (confirmed by  m. costabel,
cf. Cc):

when viewing a pdf-file, the file is initially correctly displayed but
`gv' allows zooming in  only if `gv' was called on a bare file name
such as:

gv some_file.pdf.

if started with a relative or absolute path in front, such as 

gv some_path/some_file.pdf

I get the error message:

------------------cut--------------------------------
Error: /invalidfileaccess in --file--

Execution stack:

in the `gv' error window. 


more precisely, e.g. for a file in my home directory:

gv some_file.pdf            -- works
gv ./some_file.pdf          -- works
gv ~/some_file.pdf          -- does not work (zooming fails)
gv /Users/vdh/some_file.pdf -- does not work (zooming fails).

on the other hand, viewing of postscript files works in either case,
i.e.


gv some_file.ps
gv some_path/some_file.ps


both work as they should. I don't have the slightest idea what is
happening.


this is with MacOSX 10.4.9. and gv 3.6.1 (installed via fink 0.27.1)).
my `.gv' file looks like

GV.antialias: False
GV.watchFile: True
GV.watchFileFrequency: 2500

I only now cornered the problem (which previously appeared to be of the
"now you see it, now you don't" variety), but think I observe this
since about 6-12 month).
