Summary: mission control crash with handler disappearing
QA Contact: telepathy-bugs at lists.freedesktop.org
Severity: normal
Classification: Unclassified

Reporter: scampa.giovanni at gmail.com
Hardware: Other
Status: NEW
Version: unspecified
Component: mission-control
Product: Telepathy
mc crashed when a channel handler disappeared (sigkilled) while another client
was ensuring that channel - ie, it crashed while replying "Handler no longer
available"
The reply was sent to the second client though.
