I did not intentionally or knowingly install libmoon. I have just got my 64-bit machine back from the shop after replacing a dead data drive and installed Lucid beta --- the first time that I have had Lucid on this machine. I tend to run a wide range of applications and have therefore installed many packages after installing from the CD. Clearly libmoon got pulled in along the way.
The large crash report from /var/crash is attached.
firefox worked fine before the large installation session. Afterwards:
Attempting to load the system libmoon
Segmentation fault (core dumped)
My basic setup is this:
bruce@Xenophon:~$ uname -a
Linux Xenophon 2.6.32-16-generic #25-Ubuntu SMP Tue Mar 9 16:33:12 UTC 2010 x86_64 GNU/Linux
bruce@Xenophon:~$ lsb_release -a
