[Evolution] Bug#800496: evolution-ews: Unable to store Host URI / OAB URI

[Yusuf Iskenderoglu]

Package: evolution-ews
Version: 3.16.3-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Currently, evolution cannot access EWS anymore and prevents me from using
company mail.

Between 2015-09-25 and 2015-09-28 some packages were updated in
Debian/unstable.
I cannot tell which one is causing the problem. I experimented on downgrading
libsoup, on downgrading
all of the parts of evolution to 3.16.3 (currently, evolution itself has a
different version
than evolution-ews [3.16.5 vs 3.16.3]).
None of them helped.

I assume, it might be related to something deeper in the dconf/dbus/glib
interaction, but for this to find out, I am not technical enough.

The problem is: After that upgrade evolution "lost" the setting of Hosturl in
the source file (in .config/evolution/sources), and is no longer able to store
it. I can enter the URL to exchange web services, I can fetch the OAB Url,
however when storing

a) I am no longer asked for a password
b) I monitored the happening with dbus-monitor and have seen that something is
returning "CredentialsRequired"
c) Evolution first displays "Timeout"
d) Evolution prints to the console "failed to commit changes" due to some dconf
timeout.
e) However, the /usr/lib/dconf/dconf-service is running
f) Using dconf-editor I can see and modify settings in dconf
g) No other gnome-application seems to have a problem

If I retry storing, evolution hangs and needs me to execute killev.
If I try to see what it is trying to open using strace, evolution hangs and
becomes unresponsive requiring me to kill strace.

It also does not help modifying the .config/evolution/sources/xxx.source file
by adding the URLs manually, somehow they are not used when starting evolution.

In the meantime: The company using the Microsoft Exchange Server did not change
the server version, nor
there was a mystical Microsoft Update.

It would be nice if somebody can point me to the right solution.
