I get a crash with libreoffice on my system, tested libreoffice-3.4.4.2-r1 and libreoffice-bin-3.4.3.2-r1. To replicate the crash I use the following procedure (reproducible every time): 1) open a new calc document 2) right click on a cell -> Format Cells 3) select the Numbers tab (it was not the default) The problem is related to the ICU 4.8.1 release, it can be fixed going back to ICU 4.8 or upgrading to 4.8.1.1 (I chose the second option). Also reported on FreeBSD (http://www.freebsd.org/cgi/query-pr.cgi?pr=162229)
with libreoffice 3.4.3.2-r1 (not bin, emerged 11/08/2011) and dev-libs/icu-4.8.1-r2 (emerged 10/20/2011) I do not see this crash. The default cell format IS numbers, but changing a column to something else, then selecting a cell and changing it back to number works fine. I'm on amd64 (mostly stable with a few ~) Is it a question of specific versions/ebuilds?
Right now I have downgraded icu to version =dev-libs/icu-4.8.1-r2. Then I have followed the instruction at http://wiki.documentfoundation.org/BugReport#How_to_get_backtrace_.28on_Linux.29 to get a backtrace report. The gdb session is attached with the backtrace of the SIGSEGV. When I switch back to =dev-libs/icu-4.8.1.1 the problem disappears.
Created attachment 298073 [details] gdb.log.gz backtrace information
Created attachment 298075 [details] emerge-info.txt.gz emerge --info
I would say this is fixed as I raised the dep to icu for 4.8.1.1
