             Bug #: 44512
           Summary: Crash when ConnectionManager is removed but account
                    still there
    Classification: Unclassified
           Product: Telepathy
           Version: unspecified
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: mission-control
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: florian.reinhard at googlemail.com
         QAContact: telepathy-bugs at lists.freedesktop.org

Version 5.9.1 (please add that one to the version list for bug reports, it ends
at 5.7)

This is not common but might still happen for broken distribution upgrades.

Steps to reproduce:
* have mission-control and e.g telepathy-gabble installed
* configure a xmpp account using gabble (tested with
kde-telepathy:ktp-accounts-kcm)
* purge the connection manager telepathy-gabble
* restart mission-control-5 (don't know if one needs that step)
* start a application using telepathy (tested with
kde-telepathy:ktp-contact-list)
* watch mission-control-5 die

Crashes on x86 and x64

Here's the backtrace i got:
