Kamalakar Agashe, thank you for reporting this and helping make Ubuntu better.
With an Acer Aspire 5750-9668, it took Xubuntu 12.10 ~1.5 minutes for the file to open. Does it ultimately open in Precise if you let it "hang"? If so, how long does it take? cd ~/Desktop && wget -c https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1065486/+attachment/3394549/+files/Daily_meeting_11th_oct.XLSX -O example.xlsx && localc --nologo example.xlsx lsb_release -rd Description: Ubuntu 12.10 Release: 12.10 apt-cache policy libreoffice-calc libreoffice-calc: Installed: 1:3.6.2~rc2-0ubuntu3 Candidate: 1:3.6.2~rc2-0ubuntu3 Version table: *** 1:3.6.2~rc2-0ubuntu3 0 500 http://archive.ubuntu.com/ubuntu/ quantal/main i386 Packages 100 /var/lib/dpkg/status It opens up near instantly via Gnumeric. apt-cache policy gnumeric gnumeric: Installed: 1.10.17-1.1ubuntu1 Candidate: 1.10.17-1.1ubuntu1 Version table: *** 1.10.17-1.1ubuntu1 0 500 http://archive.ubuntu.com/ubuntu/ quantal/universe i386 Packages 100 /var/lib/dpkg/status It took ~20 seconds for Microsoft Office Professional Plus 2010 Excel Version 14.0.6023.1000 (32-bit) to open it. wine ~/.wine/drive_c/Program\ Files/Microsoft\ Office/Office14/EXCEL.EXE /e example.xlsx apt-cache policy wine1.5 wine1.5: Installed: 1.5.12-0ubuntu1 Candidate: 1.5.12-0ubuntu1 Version table: *** 1.5.12-0ubuntu1 0 100 /var/lib/dpkg/status ** Changed in: libreoffice (Ubuntu) Importance: Undecided => Low ** Changed in: libreoffice (Ubuntu) Status: New => Incomplete ** Summary changed: - Libreoofice hangs while opening xlsx file + Calc hangs while opening xlsx file -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1065486 Title: Calc hangs while opening xlsx file Status in “libreoffice” package in Ubuntu: Incomplete Bug description: $ lsb_release -rd Description: Ubuntu 12.04.1 LTS Release: 12.04 Version: libreoffice-calc 1:3.5.4-0ubuntu1.1 I installed libreoffice-dbg 1:3.5.4-0ubuntu1.1 and followed instructions. $ soffice --backtrace and opened the xlsx file and libreoffice hanged.
