Your backtrace mentions libnss_ldap many times. I don't know if the bug is in nss_ldap or in konquerors interaction with it.
I followed the instructions found in the debian wiki to build packages with debug information (HowToGetABacktrace) to build my own libnss-ldap package, and got a more complete (and rather lengthy) backtrace. It's pasted at the end of the message.
I don't have nss_ldap installed so it is not something directly needed for konqueror.
I'm experiencing this problem in my computer at work, where LDAP is used.
I don't know your setup, but if you have the possibility to try remove libnss-ldap package, it might help
I'm afraid I cannot. New backtrace: Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
