What are the the -debuginfo packages? For VLC, all I see is vlc and  
vlc-devel for packages. Do I have to compile my own build of VLC?  
What about X? Sorry, I'm not yet intimately familiar with rpm/yum  
package management.

As for gdb, I do have the hang of it I think, but there are tons of  
"no dubugging symbols found" lines . I'm assuming due to the lack of - 
debuginfo. The only interesting line (other than thread-related  
things) showed up after the segfault and is:
0x00002aaab4e73606 in mpeg2_idct_init () from /usr/lib64/libmpeg2.so.0
