Is Nemo 1.1.2 leaking memory?

[oscarus]

I'm running Linux Mint 14 (Cinnamon,64-bit) and I've noticed that Nemo has a tendency to use more and more memory every time I perform certain actions such as opening new windows or emptying the trash. Nemo usually starts using around 25Mb, but the number keeps rising, and after a few days of doing some basic file managing tasks (I don't deal with huge files or folders, smb transfers, or lots of thumbnails) the memory jumps to around 300Mb and higher.

I tried to replicate my problem in this video to give you an idea of what happens when I open and close a folder:
http://www.youtube.com/watch?v=eCYEZLBTt5c
(notice that closing windows doesn't free any memory)

So my questions are:

Is this normal?
Is this something I should be worried about?
Is anyone else experiencing similar things?
I read a bit about memory usage (stuff like linuxatemyram.com) but I'm not sure if that's related to this... Does this behavior have anything to do with some weird caching stuff or something like that?
Is there a possibility that gtk+ themes or icons could have something to do with this? I was using the faience theme but switched to Mint-x because it was making the memory use worse.

I'd really appreciate any help or information regarding this issue.

On an additional note, I just restarted my laptop (right after I recorded that video) and noticed that cinnamon is using a lot less memory than what is shown in the video (it's using 90MB now vs the 254 MB in the video) but I wasn't as concerned about it because takes cinnamon a while to reach that compared to nemo.

I can confirm this behavior.

I'm running Linux Mint 13 (Cinnamon, 64-bit) with backports enabled. At this point, with an uptime of 8 days, and a bunch of appications open, nemo is up to 4.5 gigs of my 8 gigs of ram, and is using about 100% of one of my 4 cores. I noticed the problem when nemo started to get slow.

My configuration is pretty vanilla, I've added a few things here and there, but the only thing [that I can think of] which would affect nemo was adding RabbitVCS for svn, using the procedure here:
http://codemonkeymagic.blogspot.com/201 ... n-and.html

I'm not sure it it is related, but I also noticed that the output of ps aux --sort -%mem does not agree with what gnome system monitor displays, insofar as CPU% for nemo and /usr/bin/cinnamon
(ps aux --sort -%mem shows /usr/bin/cinnamon as using 79% of the CPU, and shows nemo as only using 0.8% (see the top 10 lines of output below), yet gnome system monitor at approximately the same time listed nemo as taking 96%, and cinnamon around 48%.

Output of ps aux --sort -%mem:

for good measure, here's the output of inxi -Fc 0

I'll be interested to hear if there is a fix.

I'm having the same problem, only Nemo chews up 3.5GB of memory (and a high CPU for about 10 seconds) when you first start it.

I discovered that it seemed to do it only when using a custom GTK theme. Changing the GTK theme back to default solved the problem.
