Comment 3 for bug 925508

The stack trace is different from the five or so similar bugs I could find, so this doesn't seem to be a dup. Here's the stacktrace:

#2 0xb6d192b5 in abort () from /lib/i386-linux-gnu/libc.so.6
#3 0xb6d4facc in ?? () from /lib/i386-linux-gnu/libc.so.6
#4 0xb6d5a892 in ?? () from /lib/i386-linux-gnu/libc.so.6
#5 0xb6d5b532 in ?? () from /lib/i386-linux-gnu/libc.so.6
#6 0xb6d5e61d in free () from /lib/i386-linux-gnu/libc.so.6
#7 0xb6f2e51f in operator delete(void*) () from /usr/lib/i386-linux-gnu/libstdc++.so.6
#8 0xb6f1599b in std::string::_Rep::_M_destroy(std::allocator<char> const&) () from /usr/lib/i386-linux-gnu/libstdc++.so.6
#9 0xb409efdb in unity::IconLoader::Impl::Iteration() () from /usr/lib/compiz/libunityshell.so
#10 0xb409f0ab in unity::IconLoader::Impl::Loop(unity::IconLoader::Impl*) () from /usr/lib/compiz/libunityshell.so

Maybe this happened when I did right-click eject on the DVD icon, then?

I've installed libc6-dbg and unity-dbgsym so if this happens again, I can provide a slightly better backtrace.
