First time filling a bug report/help request for osc, so I'm not sure if this
is the correct bugzilla category for it, and apologies if it's not.

I'm trying to branch out SLE12's btrfsprogs package with osc like this:

fdmanana 10:25:02 ~/tmp > osc -A https://build.suse.de/ search btrfsprogs
No matches found for 'btrfsprogs' in projects
####################################################################
matches for 'btrfsprogs' in packages:

# Project                                      # Package

(...)

I can't tell what the problem is. This happens on 2 different machines running
openSUSE 13.1, with osc installed with "zypper install osc". I have the correct
credentials in ~/.oscrc:

fdmanana 10:27:56 ~ > egrep -A 3 'build\.suse\.de' ~/.oscrc 
[https://build.suse.de]
user=fdmanana
pass=<my password here in plain text>

fdmanana 10:28:01 ~ > 


If I go to the web interface of https://build.suse.de, I'm able to login using
the same exact credentials that I have in .oscrc and through there I can branch
btrfsprogs.

Tried both with osc 0.151 and 0.152.

I'm on our internal IRC, with nick "fdmanana", in case it helps to solve this
more quickly.

Thanks!
