Bug 284721

Application: rekonq (0.7.90)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

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

1) Open rekonq.
2) Go to http://rutracker.org/
3) Wait until page is completely loaded
4) Refresh the page and again wait until page is completely loaded

Refreshing the page (step 4) always causes rekonq crash on second of third time. It is a bit strange that stack trace contains lines related to flash pluging because the crash occurs if manual plugings loading enabled. It never occurs if plugins are disabled.


- Custom settings of the application:
Manual pluging load is set.

The crash can be reproduced every time.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
