Default VLC + projectM visualisations = segfault

Yes. It seems to be a common problem for many distros. The searching of google
suggests the only solution is to compile from source and turning off (something) I
leave that for you to research.

Yes, you should.

Stop here, please. Don't rush like that. Anyone else, who finds this
message in the list archives (when searching the Internet), don't run
a command like that. Not only does it install much more than necessary
(even packages for software development), VLC already depends on libprojectM.
And that could have been checked verify easily. Homework time:

Query the names of all installed rpms to see whether one contains "projectM":

$ rpm -qa|grep projectM
libprojectM-2.0.1-14.fc17.x86_64

Or without grep:

$ rpm -qa *projectM*
libprojectM-2.0.1-14.fc17.x86_64

Or if you're unsure about upper-case/lower-case spelling:

$ rpm -qa|grep -i projectM
libprojectM-2.0.1-14.fc17.x86_64

Feel free to examine this package further to figure out what it includes
and what it does. There are many ways to check for dependencies, but
a convenient one for newbies is this:

# sudo rpm --erase --test libprojectM
error: Failed dependencies:
libprojectM.so.2.0.1()(64bit) is needed by (installed) vlc-2.0.1-1.fc17.x86_64

And voila! You've just found out that "vlc" needs this package already.
No need to install anything named *projectM* manually.

It has been there before.

Yes, it does. And interestingly, ABRT does not intercept that segfault.
I've had lots of trouble with libprojectM when Audacious still included a
visualization plugin based on projectM.

The crash has been reported before, albeit the initial comments are
out-of-date (as the font-does-not-exist problem has been fixed long ago):

https://bugzilla.redhat.com/664088

A newer libprojectM is available upstream, too.

/usr/bin/projectM-pulseaudio from package "projectM-pulseaudio"
works, though. A closer look will be necessary.

You could spare the patronizing, lecturing tone. Really. Disk space is cheap, I have 1TB of free disk space for heaven's sake. installing everything related with ProjectM spares me the hassle of having to re-download some missing bit later on (for instance now that I'll have to attempt to compile source code on my own to see if the bug is fixed).
