            Bug ID: 304417
          Severity: crash
           Version: 0.14.3
          Priority: NOR
          Assignee: okular-devel at kde.org
           Summary: Okular crashed when choosing printer
    Classification: Unclassified
                OS: Linux
          Reporter: research at science.su
          Hardware: Debian unstable
            Status: UNCONFIRMED
         Component: general
           Product: okular

Application: okular (0.14.3)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.4.3-pf x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
This crash usually happens when there are few printers available (real or
virtual like PDF output - does not matter) and I want to use non-default
printer and choose wrong one once or twice. Then it will crash when I try to
choose (from drop-down menu) one more time. This crash especially likely to
happen if I go to Properties every time before choosing another printer.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
