gnome-keyring memory use (leak?)

[Otus]

I see gnome-keyring-daemon using hundreds of meabytes after just a few days of uptime. Here's one with weeks of uptime:

90 MB RSS and 300 MB in swap when I've had plenty of memory free suggests there's a lot of data that is not actually used. (If I'm interpreting the above correctly, the most that's ever been in use at the same time is 200 MB.)

Maybe a memory leak?
