Incorrect key file for table

[Jørn Dahl-Stamnes]

Hello,

While doing a select query I  got the following error in the error-log file:

    Incorrect key feil for table '/tmp/#sql_5f8_0.MYI'; try to repair it

It seem rather meaningless to try to repair a temporary table... So is this a 
bug in MySQL, or?

The database I'm using has only InnoDb tables and I'm using version 
5.1.42-log.
The query is build using Propel (from a web-application made by Symfony 
framework).
