Bug Description

This is the exact same bug as debian bug 366660:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=366660

This is already fixed in edgy (because of folding in the upstream changes), but dapper still has the problem.

This is a severe problem, because of the potential for data loss. One of my users has already experienced data loss because of it.

This is the debdiff that I just uploaded. It only moves the input file unlinking to a later point in the code (after a successful close() call). I verified that the updated package still works and behaves normally. Unfortunately the actual bug is hard to reproduce, one would need to trigger a failure of close(). Thus verification efforts should concentrate on testing the normal functionality to check for regressions.

Waiting in dapper-proposed UNAPPROVED queue now for acceptance.

I have used the actual dapper-proposed .debs in my dapper vmware for about a month, and it still works fine.
