Subject: qconf: reproducible segfault


Not a big deal (I just discovered 'make gconfig'), but I'm experiencing
a reproducible segfault in 'make xconfig', i.e. qconf.

I was wondering if anyone else can reproduce this:

1. QTDIR=/usr/local/lib/qt make xconfig
    mine by default has all qconf options OFF ('Show Name', 'Show Range',
    'Show Data', 'Show All Options', 'Show Debug Info')

2. from the kernel options, select:
    Networking / Networking options / Network packet filtering (replaces ipchains)

3. from the qconf options, now select 'Show Debug Info'
    voila -> segfault


This is with qt-3.3.3:

First I thought qconf window geometry and maybe font would make a
telling difference here, but I can resize the window all I want and
change fonts any which way I can, but the segfault persists.

FWIW, my initial geometry is 957x843, font is usually LuciduxSans 7.

Strace output didn't provide much of an apparent clue, just the
SIGSEGV.

Oh, kernel is 2.6.19.1 -- not important I'd say.

Thanks for your time.
