Hm, this was some confusion about packages it seems. I had a version of istanbul in /usr/lib/python2.4/site-packages, which was loaded and used instead the version from /usr/share/python-support. I'm not sure, wether this was an error of the packages or me, because i had a manually installed version of istanbul once.
After apt-get remove and install again, istanbul starts as expected. Probably my own fault, so this bug can be closed. Thanks for trying to reproduce it. :) -- doesn't start but crash https://launchpad.net/bugs/60616 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
