Version:           3.1.0 (using KDE KDE 3.1)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc version 2.95.4 20011002 (Debian prerelease)  Though Debian is transitioning to gcc 3.2 the package names imply QT etc. is still using 2.95 C++ linking conventions
OS:          Linux

Hi there; pretty much every Konqueror window that I open, filesystem, network etc. will crash Konqueror with a signal 11 and the backtrace below.  Some pop-up windows from web pages allow themselves to be closed without incident (thankfully) but otherwise the effect is that I get a crash window pretty much every time after I close a Konqueror window.

This is from the very latest Debian/unstable distribution of Konqueror which a friend has also got on his laptop, but his version seems fine (i.e. we've both done apt-get dist-upgrade last night, and get different behaviour from Konqueror).  So it's presumably an interaction with something on my machine but I'm not sure where to start looking.  ldd /usr/bin/konqueror shows no local libraries, everything has come from Debian:
