Not possible to assign trust to a previously un-trusted certificate

[despens]

This happened:

1. Connect to captive portal
2. owncloud sync client complains about wrong certificate, distrust certificate
3. back on normal internet
4. accidentally click on option to revoke trust from correct certificate
5. owncloud won't connect anymore

what should have happened: offer obvious way to manage certificates

OS: Ubuntu 14.04, Gnome Shell

sync client:

$ dpkg --list | grep owncloud
libowncloudsync0:amd64 2.1.0-1.1 amd64 the ownCloud sync library
owncloud-client:amd64 2.1.0-1.1 amd64 The ownCloud sync client - github.com/owncloud/client
owncloud-client-l10n 2.1.0-1.1 all Internationalization files for ownCloud

General at a loss what to do now :)

Just stumbled over the same problem.

Another interesting thing is that beside the badge saying "Keine Verbindung zu ownCloud auf ... Im Ablauf des SSL-Protokolls ist ein Fehler aufgetreten" there is a button labelled "Benutzerkonto". You can click on it and there is a menu entry similar to "connect". If you click it, you get the message that you are now disconnected. Clicking "connect" again fails without an error and the menu entry still exists. ;)

BTW: Closing and reopening the client worked for me.
