This problem is occuring on Gentoo Linux but I suspect it might happen on other distros. The problem occurs when VLC is built using Gentoo's portage system, as well as, manually (i.e. configure ; make). Running vlc when the current directory is the vlc source directory works fine but if I cd to somewhere else and run vlc it produces a "Segmentation fault". It doesn't matter if I try to run the vlc binary installed on the system by portage or the one in the source directory built manually. It also doesn't matter which symbolic link (qvlc, gvlc, kvlc) I use to run the program Here is the gdb backtrace: (gdb) run Starting program: /usr/local/bin/vlc VideoLAN Client 0.6.0 Trevelyan [New Thread 16384 (LWP 20336)] Program received signal SIGSEGV, Segmentation fault.

(y or n) ----- VLC was built from source using the following configure options: ./configure --enable-svgalib --disable-fb --disable-dvd --disable-dvdread --disable-dvdplay --enable-alsa --enable-arts --enable-esd --disable-nls --disable-gtk2 --enable-kde --enable-qt --enable-ncurses --disable-slp --enable-v4l --enable-faad --enable-a52 --enable-dvbpsi Using the '--disable-kde' option to configure does fix the problem, however, I no longer have the KDE interface, which is what I want to use. Next, I figured I would use the QT interface instead but it produces a segmentation fault as well but only when I run VLC with the symbolic link qvlc.

Exit anyway? (y or n) ----- I am using KDE 3.1.2 and QT 3.1.2. This bug report has also been submitted to VideoLAN as bug ID 1055. http://bugzilla.videolan.org/cgi-bin/bugzilla/show_bug.cgi?id=1055
vlc-0.6.1 has been added to portage. Please this new ebuild and let me know if you still have problems. I have been able to utilize all interfaces wxvlc, vlc, gnome-vlc, svlc, qvlc, kvlc, and the mozilla plugin interface as well.
I've emerged vlc-0.6.1 (Portage Version 20030620). I'll test it out and report back later.
I have emerged vlc-0.6.1 and tested. VLC now appears to be working properly using the KDE and QT interfaces. BTW: 'emerge -s vlc' indicates the version installed is "20030620" not "0.6.1".
vlc-0.6.2 is now in portage as well. Good to hear that things are working for you. :)
