Just tripped over a to me unexpected behavior in the curl client. When combining the --silent and the --show-error options they apparently have to be used in just that order for the errors to actually be show.
andreas@pingu:~$ curl --show-error --silent http://complete.bogus/
andreas@pingu:~$ curl --silent --show-error http://complete.bogus/
curl: (6) Couldn't resolve host 'complete.bogus'
andreas@pingu:~$
In case this actually is a desirable behavior it might be nice to have it mentioned in the man page.
The curl version in question is taken fresh of the master branch.
andreas@pingu:~$ curl --version
curl 7.23.0-DEV (x86_64-unknown-linux-gnu) libcurl/7.23.0-DEV OpenSSL/1.0.0e zlib/1.2.3.4 libidn/1.22 librtmp/2.3

I'd say this is _not_ a desirable behavior. I'll work on a fix..
Thanks for your report. This bug has been fixed in commit b229c8ca8b34d which has been pushed to the git repo.
Case closed!
