After installing libreoffice-3.4.3 from the editors/libreoffice port, and removing user's ~/.libreoffice, I've tried to launch 'libreoffice'. First results are:

javaPathHelper: not found
Warning: failed to launch javaldx - java may not fuction correctly
Segmentation fault (core dumped)

This is the oosplash.bin coredump, reason: Program terminated with signal 11, Segmentation fault; backtrace is:

(gdb) bt

#1  0x00000000004038f2 in splash_draw_progress ()
#2  0x00000000004068ff in main ()

But the main problem is that when I select Text Document -> click Font Name, soffice.bin crashes instantly, reason is also: Program terminated with signal 11, Segmentation fault; backtrace is:

The editors/libreoffice port was built with the options GTK=on and SYSTRAY=on.
My locale settings are

dmitry@lynx$ locale
LANG=uk_UA.UTF-8
LC_CTYPE="uk_UA.UTF-8"
LC_COLLATE="uk_UA.UTF-8"
LC_TIME=C
LC_NUMERIC=C
LC_MONETARY=C

LC_ALL=

I've built libreoffice-legacy-3.3.3_3 on the same system from the same ports tree, and it does not exhibit such problems in the same environment (the only startup message is 'javaPathHelper: not found').
