+When dealing with beaming that is not correct (eg quarter notes in

+a good solution is quite a lot of work.

+LilyPond occasionally crashes while parsing the initialisation files.
+This is a very obscure bug, and usually entering the commandline
+differently "fixes" it.

+[Linux Intel]
+
+A problem resembling the previous: usage of libg++.2.8.x with the
+wrong version of libc results in a coredump from the scanner while
+reading the init files.  Stacktrace:
