Hi... Thanks for the report. It would be very helpful if you could provide a bit more information (as we obviously can't test it ourselves in this case). 
In particular:
1) Please install debug packages as described here:
http://techbase.kde.org/Contribute/Bugsquad/How_to_create_useful_crash_reports
so we get line # information on backtraces
2) Install valgrind, from your distro's packages
3) Run "valgrind konqueror --num-callers=32 &>log" from a terminal, and try to reproduce the bug, then attach the log file here. It'll be quite slow, but it will likely diagnose exactly what's going on wrong.

Thanks again!

@Maksim: are bug 223739 and bug 227360 also related to this? (seems so) Regards
