Sounds like an issue in python itself, or perhaps in glibc. Is /dev/shm mounted as tmpfs? glibc uses that for POSIX shared memory and semaphores. Also, you might want to try rebuilding dev-lang/python:2.7; it might be that sem_open was mis-detected by configure when last you built it. afaik, this is a bootstrap issue. You most likely installed your system from an environment which didn't allow python to compile with detecting needed libraries/headers/whatever to enable proper threading support. Just rebuild python and you should be fine. (In reply to Gilles Dartiguelongue from comment #4) > afaik, this is a bootstrap issue.

Probably I was building python last time on a systems without systemd and udev, therefore(?) the shared memory was not recognized After rebuilding python-2.7.5-r2, python-3.2.5-r2 and python-3.3.2-r2 the issue with meld disappeared. I would bet on the old libc for some reason. I had the same problem bootstrapping a gentoo system from a debian squeeze... :) *** Bug 496332 has been marked as a duplicate of this bug. *** (In reply to Mike Gilbert from comment #3) > Also, you might want to try rebuilding dev-lang/python:2.7; it might be that > sem_open was mis-detected by configure when last you built it. I rebuild both python-2.7.5-r3 and 3.3.2-r2 but it doesn't help in my case I still get the same error: meld phone_book.txt Traceback (most recent call last): File "/usr/bin/meld", line 173, in <module> main() File "/usr/bin/meld", line 165, in main new_window = app.parse_args(sys.argv[1:]) File "/usr/lib64/meld/meld/meldapp.py", line 169, in parse_args tab = open_paths(args, options.auto_compare, options.auto_merge) File "/usr/lib64/meld/meld/meldwindow.py", line 791, in open_paths self._single_file_open(a) File "/usr/lib64/meld/meld/meldwindow.py", line 781, in _single_file_open doc.set_location(path) File "/usr/lib64/meld/meld/vcview.py", line 395, in set_location self.choose_vc(vc.get_vcs(os.path.abspath(location or ".")))

ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770. issue 3770 seems to be connected with http://bugs.python.org/issue3770 . It happens only on one system. Is this connected with a kernel option or is it a python problem?
