This code checks if a known bug in some PyQwt versions affects your installation.
Simply run this script and see the diagnosis in the std output.
If you are affected, the solution is to install/compile a newer version of PyQwt/SIP
Notably, the python-qwt5-qt4 package originally shipped with
Ubuntu 10.10 is affected
In some systems, the bug produces a segfault while in some others it
produces an Assertion error similar to the following:
python: /build/buildd/sip4-qt3-4.10.5/siplib/siplib.c:2600: sip_api_parse_result: Assertion `assign_helper != ((void *)0)' failed.

Hi Frederic
Now python-sip and python-qt4 have been updated and your problem seems to
be solved so I close the bug.

Gudjon
