Description:
Gajim is not able to read operating system information due to the empty /etc/arch-release file..
The bug has been fixed in gajim and the gajim package for archlinux should beupdated

http://trac.gajim.org/changeset/9283

Additional info:
* The bug was recently fixed and the new version is in the svn repository



It should be enough just to change the following function in the file /usr/share/gajim/src/common/helpers.py :

def get_os_info():
if os.name == 'nt':
ver = os.sys.getwindowsversion()
ver_format = ver[3], ver[0], ver[1]

(2, 4, 0): 'NT',
(2, 5, 0): '2000',
(2, 5, 1): 'XP',
(2, 5, 2): '2003',
(2, 6, 0): 'Vista',
}
if win_version.has_key(ver_format):
return 'Windows' + ' ' + win_version[ver_format]
else:

return output

for distro_name in distro_info:

# yes, then run it and get the first line of output.

else:

text = fd.readline().strip() # get only first line
fd.close()

# sourcemage_version and slackware-version files
# have all the info we need (name and version of distro)
if not os.path.basename(path_to_file).startswith(
'sourcemage') or not\
os.path.basename(path_to_file).startswith('slackware'):
text = distro_name + ' ' + text
