Same issue here.

Version:
ownCloud version 2.3.2
Git revision 820899d07102b990b19e8b02121221e41f7fbf06
Using Qt 5.9.1, built against Qt 5.7.1
Using 'OpenSSL 1.0.2g 1 Mar 2016'

Way to reproduce the behaviour:
1.) Open a freshly installed owncloud-client.
2.) Close the wizard that guides through the configuration of the first account
==> you will end up in a client without possibility to ad accounts since the "add account" button is only available from another account's tab
