I guess the intention of your note on these logs "may not contain enough
info to file a bug" is to proactively prevent people from filing bugs
with insufficient info.  But still, that sentence hangs in the air for
me, I don't know what to do with it as a newbie bug-reporter :-)
(Perhaps it's a "bear in mind to not rush to file a bug".)

With the awkward phrasing fixed:
