Application: rekonq (0.4.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic i586
Distribution: Ubuntu 10.04.4 LTS

-- Information about the crash:
Rekonq is fine until an attempt to open any https URI.  Same thing happens with Arora and Midori.  Try duckduckgo--does it every time.  Similar but not identical problem with Chromium caused me to install these.  Running Lubuntu 10.04 on an AMD K6-II 450 MHz machine; had problems with illegal instructions before, due to gc library updates.

The crash can be reproduced every time.

 -- Backtrace:
Application: rekonq (rekonq), signal: Illegal instruction
