Comment(by otto at kolsi dot fi):

 After opening this ticket I've upgraded hardware and rebuilt a frontend
 upgrading from FC5 -> FC8. With the new system it seems that none of the
 Myth visualizers crash, only some of the libvisual visualizers. All the
 others than those mentioned below seem to work fine even when 'tortured'
 with repeated changes etc.

 Some libvisual visualizers output errors before/during crash, e.g.:

 '''nastyfft:'''
 {{{
 /usr/local/bin/mythfrontend: symbol lookup error:
 /usr/lib/libvisual-0.4/actor/actor_nastyfft.so: undefined symbol:
 visual_mem_malloc0
 }}}

 '''gdkpixbuff:'''
 {{{
 (process:5946): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion
 `src != NULL' failed
 libvisual CRITICAL: mythmusic: update_scaled_pixbuf(): assertion
 `priv->scaled != NULL' failed
 }}}

 '''gforce:'''
 {{{
 libvisual CRITICAL: mythmusic: mfl_DestroyFont(): assertion `f != NULL'
 failed
 }}}

 '''jess''' crashes and doesn't output anything. Backtrace of one of the
 crashes is attached.

 I think the original problem for me has either been solved by some
 changeset or the system upgrade solved it. Can someone confirm from the
 latest backtrace that the crash does not occur within MythMusic? And
 finally, if libvisual component crashes, there is no point taking
 backtraces since nothing can be done within MythMusic?
