           Summary: ktp-text-ui  sometimes crashes on new message
    Classification: Unclassified
                OS: Linux
          Reporter: clee at kde.org
          Hardware: Ubuntu Packages
            Status: NEW
         Component: text-ui
           Product: telepathy

Application: ktp-text-ui (0.3)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64

-- Information about the crash:
I was logged into a jabber chat room and sent a message to the room. Does not
happen every time, but often enough to be really annoying.

The crash can be reproduced some of the time.
