kernel BUG on trying to open .ps file (possibly relating to openafs)

[clark3934]

I just saved a plain html webpage to a .ps (on my desktop) via firefox. When attempting to open (by clicking) I get the following error: "kernel BUG at /usr/src/modules/openafs/src/libafs/MODLOAD-2.6.31-14-generic-MP/osi_file.c:87!"

I'm not sure how/why this relates to OpenAFS, though. This bug is repeatable.
