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:

I can't reproduce it with FC6's current qt-devel in 2.6.20-rc3-git3...
but point 2 is in my tree

Networking / Networking options / Network packet filtering framework (Netfilter)

hmm, curious - let me download 2.6.19.1 and apply it... ok, now I see
your point 2, but I still can't reproduce the problem (Show Debug Info
does indeed show, well, debug information).

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.

I guess you'll have to try a more recent qt-devel version :)

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.

Ciao,
