Joerg,
Later this evening or tomorrow we'll post a beta that has the fixes for this problem for you to try on Ubuntu. When its ready, the centos6_x86_64 build will appear in this directory:

Dear freesurfer administrators,
recently upgraded our system to freesurfer 5.2 on lubuntu 13.04. After the installation I accounted problems when testing freesurfer. tkmedit did not display the subject bert, instead an error message was shown:
tkmedit bert orig.mgz
=================================== ERROR: A segfault has occurred. This is not your fault, : but is most likely an unrecoverable error and has : made the program unstable. : : Please send the contents of the file .xdebug_tkmedit : that should be in this directory to freesurfer@nmr.mgh.harvard.edu : : Now exiting... :
Content of .xdebug_tkmedit is:

As I found in the web this problem seems to be due to mri_convert on fedora 18 (https://bugzilla.redhat.com/show_bug.cgi?id=905638). This bug is know reproduced for lubuntu 13.04. The output if mri_convert ist called is the following:
cd $SUBJECTS_DIR mri_convert sample-001.mgz test.mgh $Id: mri_convert.c,v 1.179.2.7 2012/09/05 21:55:16 mreuter Exp $ reading from sample-001.mgz... Segmentation fault (core dumped)
Is there a bugfix?
Sincerely yours
Joerg
