vlc 0.8.2: segmentation fault after the start. Bug?

[vitaly_r]

I can't start the latest vlc (0.8.2) compiled from the sources.
The previous vlc version runs fine.

I see the following after issuing the command "vlc -vvv":

Segmentation fault

What's the problem?

The problem is not related to permissions - result is the same for root and other users.

Thanks a lot for your help.

Hello!

New data: I've found the cause of this error:

main vlc warning: cannot load module '/usr/local/lib/vlc/gui/libwxwindows_plugin.so' (/usr/local/lib/libgtk-x11-2.0.so.0: undefined symbol: atk_object_add_relationship)
[00000001] main vlc warning: cannot load module `/usr/local/lib/vlc/gui/libwxwidgets_plugin.so' (/usr/local/lib/libgtk-x11-2.0.so.0: undefined symbol: atk_object_add_relationship)
[00000001] main vlc warning: cannot load module `/usr/local/lib/vlc/misc/libxml_plugin.so' (/usr/local/lib/vlc/misc/libxml_plugin.so: undefined symbol: xmlReaderForIO)

These messages can be read after calling vlc with "--reset-plugins-cache --verbose 4" options

If I issue the command "LD_PRELOAD=/usr/local/lib/ ... vlc " all is correct (OK). Hmm. Now I have the following questions:

1) How can I avoid 'LD_PRELOAD'? The output of 'ldd libwxwidgets_plugin.so | grep atk' is:

libatk-1.0.so.0 => /usr/lib/libatk-1.0.so.0 (0x40b61000)

But it should point to '/usr/local/lib/libatk-1.0.so.0'!
How can I do this? (There are two versions of atk/gtk/pango/glib on my system - I can't change this situation. Old versions are located in '/usr/lib' while new versions ae located in '/usr/local/lib')
2) Should I report a bug? It seems to me it is not a good behavior to get segmentation fault in this situation.
3) I see many warnings like the following:

main module warning: cannot find symbol "vlc_entry__0_8_2" in file `/usr/local/lib/vlc/codec/libspeex_plugin.so' (vlc: undefined symbol: _vlc_entry__0_8_2)
main module warning: cannot find symbol "vlc_entry__0_8_2" in file `/usr/local/lib/vlc/demux/libnsc_plugin.so' (vlc: undefined symbol: _vlc_entry__0_8_2)

What can I do with them?

Thanks a lot & Good bye!
