Application: kspread (2.3.1)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.5-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I opened a spreadsheet that had been created by Libreoffice.  It had some formatting in the file.  I resized some of the columns and rows.  I then wanted to delete some rows.  Selecting two or three rows to delete, right-clicking on one of the row numbers, I selected delete rows.  It then messed up the formatting directly above the deleted rows.  It would span the deleted rows into the row above it.  I tried to delete some more rows, farthur down the list, and it did something funny.  I then clicked ctl-z to undo a couple of times and the application crashed.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KSpread (kspread), signal: Segmentation fault
