It executes in 0 sec when you run it. It might be in the query cache.
Try it with SQL_NO_CACHE. But even then it might run faster than it
did when it got logged in the slow log, because the table's data might
be in memory and therefore faster to access.
The point is that the slow query log show

I'm just guessing, but if the slow query log time resolution is seconds,
perhaps 0.5 and higher rounds up?
Or, perhaps it has an index, but it can't be used in that query.
What does EXPLAIN [paste query here] tell you?

Wow! 70k files in /tmp. Hell of a mistake :) I hope it doesn't happen often.

hi again,
for those that are interested: the problem was indeed the filesystem
with slow lookups of BIG directories (this had nothing to do with mysql
but caused much iowait and therefore the mysql process had been heavily
impacted).

Thank you for your answer.
But is there a chance to be able to do it one day?

Hello.
You have an application which executes prepared statements.
See:
http://dev.mysql.com/doc/mysql/en/c-api-prepared-statements.html
MySQL doesn't log to the slow log a prepared statement. You
can enable general query log which logs prepared statements.

Hi,
I think log-slow-queries belongs in the [mysqld] section of my.cnf, not
[mysqld_safe].
Hope that helps.
