Comment 1 Vitezslav Stejskal 2008-06-23 14:19:12 UTC 
Strange, it's probably some sort of initialization problem in MimeLookup. There was no Preferences instance in
MimeLookup, which should never happen if o.n.m.e.settings.storage is loaded. I'll check the tests, but if it's random
then the module should be there.
Comment 3 Vitezslav Stejskal 2008-06-25 12:04:44 UTC 
There was a race condition in MimePathLookup.
