            Bug ID: 371058
           Summary: Too many double clicks on canvas cause crash
           Product: calligraflow
           Version: 2.9.11
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: yue....@mail.com
          Reporter: xionbox33...@gmail.com

Application: calligraflow (2.9.11)
KDE Platform Version: 4.14.24
Qt Version: 4.8.7
Operating System: Linux 4.7.6-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

I was trying to select a "wave" pattern which was tough to select via
double-click. Hence, my selection cycled severals times between that small
item, the bigger item which surrounded it and the blank canvas.

-- Backtrace:
Application: Flow (calligraflow), signal: Segmentation fault
