tiny patch for camel-imap-store-summary.c

["Dirk-Jan C. Binnema" <dirk-jan binnema nokia com>]

Hi Philip,

I got these valgrind warnings, apparently related to the recently
added namespace code:

 Thread 1:

It seems we trying to free an unitialized is->namespaces there.
I think it's due to a typo... see the patch.

Can I apply?

Best wishes,
Dirk.
