I agree that mozilla-thunderbird should not leave this stuff in the environment when invoking external programs. Ideally, it would be compiled with appropriate rpath options to make setting LD_LIBRARY_PATH unnecessary.
Note that firefox itself almost certainly has a similar bug: it leaves LD_LIBRARY_PATH containing /usr/lib/firefox when it runs external programs. ** Changed in: mozilla-thunderbird (Ubuntu) Importance: Undecided => Low Status: Unconfirmed => Confirmed -- Opening firefox by clicking on links in thunderbird breaks https https://launchpad.net/bugs/57923 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
