Bug 286451

Application: rekonq (0.7.0)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-7.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

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

I had entered some data in a relatively large form, and when I tried to submit it, rekonq crashed. This caused the loss of all the data I had entered, so it is potentially quite dangerous. However, I was unable to replicate it with the same form or any others. Hopefully there will be something useful in the backtrace.

The crash does not seem to be reproducible.

-- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
