Some tests on Ubuntu 9.04 today revealed the bug that grumbel had
reported on IRC.
The problem: the SEGFAULT is inside libltdl, so I am not sure how to
work around this:

Here's part of the stack trace:

Guess I might have to disable optimization and enable debugging for
libltdl to dig deeper into the issue.
I'll keep you updated. What's weird is that all C++ test programs run
fine, but all Python scripts trigger the SEGFAULT.
