Should be fixed now.

Changes have been made in CVS for this ticket:

Ensure lat/lng values remain as doubles
Bug: 9180
http://cvs.horde.org/diff.php/ansel/lib/Exif.php?rt=horder1=1.41.2.12r2=1.41.2.13ty=u

This is fixed, though in Horde 4 only right now. The exif code was 
completely rewritten in Horde 4, so I still need to trace where this 
is happening in Horde 3.

Changes have been made in Git for this ticket:

Don't perform any string operations on the variable when we assume 
it's the decimal value.
Just cast it outright, don't trim() or replace the ordinal indicators 
if present, the
cast operation will do that for us, and as a bonus, won't corrupt the 
value if it's in
a locale that doesn't use a decimal point for a decimal seperator.

it's definitive a locale issue:
when i change my language to 'English (US)'
i can import correct:

i even get before the SQL Update:

lng -6,179697 [pid 330 on line 2370 of 
"/usr/share/psa-horde/ansel/lib/Ansel.php"]
so the sql execute is converting one value and not the other?
since both are varchar in DB, i would expect both to contain , as separator?

my local should be german, i did some debug logging:
Aug 18 08:54:21 HORDE [debug] [ansel] degtodecimal(56/1,48,29,3 is

so i seem to have , as the decimal separator, but in the Lattitude 
case that's correctly convertet to . whereas in the longitude case, 
it's not ?!
Moreover both the attributes in ansel_image_attributes and the 
image_longitude  in ansel_image show the same behavior (lattitude ok, 
longitude wrong)

In Ansel/lib/Exif.php, in the function _parseGPSData (should be around 
line 131) - can you find out the value of $data, $min,  and $sec?

something like var_dump($data) etc... right before the return on line 152.

This image imports fine for me both with and without exif extension enabled:

56° 48' 29.30" N 6° 10' 46.91" W

Possibly a locale difference, I'll look and see what I can find.

ok
exif is installed:
EXIF Support => enabled
EXIF Version => 1.4 $Id: exif.c,v 1.162.2.2 2004/11/10 01:44:28 iliaa Exp $
Supported EXIF Version => 0220
Supported filetypes => JPEG,TIFF

Hm. Nothing attached, maybe a size limit on the server. Can you try 
with a smaller image?

Can you instead check your phpinfo? I don't think it's checked for in 
Ansel's test. You can check by looking at horde/test.php then clicking 
view phpinfo.  See if there is a section titled "exif".  (We don't 
require the extension, as we have our own code to fall back on, but 
this will help me determine which code to look at).

Yes, one (big) example attached :-)

No, i dont think so,
ansel/test.php says:
PEAR Modules

     * PEAR Search Path (PHP's include_path):   
/usr/share/psa-horde/lib:/usr/share/psa-horde:/usr/share/psa-horde/pear:.
     * PEAR: Yes
     * Recent PEAR: Yes
     * MDB2: Yes

Can you upload an image that this is happening with? Also, does your 
PHP have the exif extension installed?

when uploading a georeferenced photo, the lattitude is importet with 
52.12345 whereas the longitude is imported as -5,6789.
This leads to the maps api script to display the foto at longitude -5.0000
