Serious Problem - db log file owner

[Petr Danecek]

hello,
first of all, let me thank you for the wonderful software which saves me
lots of time and sorts out hundreds of spam emails a day!

it mostly works very well, but once a month or so, the berkley db
creates a new log file in the ~/.bogofilter directory which is owned by
root and not by the user. as a consequence, i get in the mailbox only
empty files!! i can only guess if they were only spams or some important
documents.

in the system maillog we get the errors
	.bogofilter/log.0000000005:_log_file_open_failed:_Permission_denied/
	PANIC:_Permission_denied.... etc


i'd like to ask how to solve this problem. so far i have not found a
helpful advice in the mailing lists.

also, i believe that bogofilter should change its behaviour - if the
underlying database fails, it should not exit cowardly, but should
stream the message instead. 

thanks for your tips,
petr danecek
