gcalctool (or its libraries?) seems to have a memory leak

[Páll Haraldsson]

I assume there is a memory leak as the old gcalctool process uses 1704 MB? Correct? Just started a new one and can't see that one with top, that far down the list. Note I haven't been doing anything complicated with the calculator, just some simple additions. May have done multiplications but not divisions or more complicated, if I recall. Probably not whole numbers all of them but not very big numbers if it matters.

[I was willing to do a coredump if something like that is needed. Does ubuntu-bug do that? If not, would it be helpful? In general does it collect all relevant info? Non-standard info/kernels/config? I have 3.11.0-17-generic running with some -proposed but mostly standard stuff. See at bottom (shouldn't/couldn't ubuntu-bug provide this?). I might delay killing it for a while unless I hear something.]

Unrelated blable per se:

Not too worried about gcalctool, you could call it an introductory bug from me. Just learning the ropes and getting a handle on things so I can submit a bug on the big one:

I was debugging a memory issue (Firefox), and was just amazed that the calculator would be the third biggest program (above Xorg!). I'm not to worried as RES should(?) affect me the most (and maybe SHR?) but VIRT is mostly on disk. However, note that I use zram and how big the swap is, not sure if it is a wise choice.

update-manager seems also to be a huge memory/cpu/network-hog (know the program is changed in 13.10). Also a memory leak or just a memory-hog?

Note how firefox shrank (didn't close anything) and how updatem-manager changes. Assume the numbers for these processes are normal.

I'm assuming newly installed memlockd is not a factor in any of this.

Stopped and started update-manager:

Just something odd:
ubuntu-bug -w

gave me:
