Thanks Julien - so your strace shows a huge amount of Java-ness happening :)
If we grep the strace log for 'open' we can see roughly what is going on:

open("/home/julien/compile-libreoffice/libo/solver/unxlngx6/installation/opt/program/../share/extensions/LanguageTool/LanguageTool.uno.jar",
O_RDONLY) = 78
30050 1330554064.750712 open("/proc/self/maps", O_RDONLY) = 78
ie. you have LanguageTool.uno.jar installed - and this is your problem :-)
30050 1330554067.076199
open("/home/julien/compile-libreoffice/libo/solver/unxlngx6/installation/opt/program/../program/pythonloader.uno.so",
O_RDONLY) = 80
After spending from 64.7 seconds to 67.08 seconds - ie. 2+ seconds initializing
java, we move onto dealing with python.
30050 1330554067.226163 open("/usr/lib/python2.7/string.pyc", O_RDONLY) = 82
The python init seems to take under 0.2 of a second.
And then we start doing crazy Java stuff again - endless parsing of
/proc/self/maps as we attach / detach that stuff.
So - this is a known bug; bootstrapping Java & LanguageTool takes ~nearly
forever :-) and there is really not much we can do about that (sadly).
