How reproducible:
Always

Steps to Reproduce:
1. Get Dell Inspiron 8600 with 802.11g card, ndiswrapper-0.7, and
bcmwl5.dll
2. Follow http://www.linuxelectrons.com/article.php/20040507104718960
(or similar from fedoranews.org)
3. Put WEP key in hexadecimal format

Actual Results:  Segmentation fault, system-config-network hangs.
Subsequent execution of iwconfig hangs.

Expected Results:  Working wireless connection.

Additional info:

Comment 1 Vadim Gritsenko 2004-06-10 12:05:58 UTC
Turns out segmentation fault was caused by WEP; once WEP key is
removed everything is working fine. This [1] also indicates that later
than 0.7 ndiswrapper should have WEP working.

Comment 3 Alan Cox 2004-06-19 11:35:23 UTC
This problem isn't in an Fedora shipped components so should be
reported upstream (if indeed its not fixed in 0.7)
