[Evolution] Bug#836804: evolution crashes when displaying any mail

[Jeff Burdges]

Package: evolution
Version: 3.12.9~git20141130.241663-1+b1
Severity: important


Evolution launches normally but if the user takes any action that would result in displaying an email, the it segfaults with the error :

(evolution:14698): GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->ref_count > 0' failed


/var/log/syslog contains messages like :
 kernel: [22296.533558] evolution[14698]: segfault at 0 ip 00007fb52d12450a sp 00007fffe8f79b20 error 4 in libgobject-2.0.so.0.4906.0[7fb52d116000+51000]


The problem was caused by libglib2.0 being pulled in from testing somehow,
apt tooling could not detect or correct the problem because it did not
recognize the conflict with evolution.  Problem was solved by running 
dpkg -i  manually on :
libglib2.0-0_2.48.0-1~bpo8+1_amd64.deb
libglib2.0-bin_2.48.0-1~bpo8+1_amd64.deb
libglib2.0-dev_2.48.0-1~bpo8+1_amd64.deb
