Memory leak in AVG email scanner

Has anyone else noticed that there seems to be some kind of memory leak in the free AVG email scanner, both version 7.0 and 7.1?

I installed 7.1 yesterday to have a look and to watch memory usage. The email scanner initially started up at around 6 mb ram use at boot time. I then received a batch of several email messages, 6 or so, some with large attachments, and after receiving them, I looked and ram usage for the email scanner was up to 18mb!!!

I had previously noticed this in 7.0 where after a day email scanner ram use was up to 33mb, which is ridiculous.

Anyone else noticed this? Or is it just on my system for some weird reason? Also, is there any way to contact the AVG people about it? Last time I looked, they offer no support for the free version, but perhaps they would be interested in bug reports?
