Version:           2.0 RC1 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

Process to reproduce :
1. Open the file

My file has 4 tabs with very simple formulas (addition) which use cell in different tabs, cell color, french language but it doesn't seem the reason because the same template in older version (and simpler) works.

Result :

KSpread Crash.

Expected Behavious :
My spreadsheet  opened in KSpread ;) !

Here the backtraces :

Application : KSpread (kspread), signal SIGSEGV
0x00007f19e5b43cf0 in nanosleep () from /lib/libc.so.6
