Application that crashed: kspread
Version of the application: 2.2 RC 1
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
Just open http://www.rockbox.org/mail/archive/rockbox-dev-archive-2010-04/att-0106/linux4nano_bounty_rev01.xls on koffice 2.2rc and you'll get the attached bactrace.

KDE 4.3.4, but also reproduced on 4.4.2.
Qt 4.6.2, libc6 2.10.2 on a Debian testing (also reproduced on sid).

 -- Backtrace:
