telepathy-sofia has serious memory leak

[Gustaf]

Binary package hint: telepathy-sofiasip

In 9.10 and in Lucid Alpha 3, telepathy-sofia sometimes, at some random time it seems, begins to swallow huge amounts of memory. It swamps the physical memory as well as swap until the machine is completely borked and unresponsive and processes gets killed (or die for other OOM-related reasons).

$ cat /proc/`pidof telepathy-sofiasip`/maps
...

Or smaps on the messed up ranges:

Just to make it clear, it happens several times a day, and it happens fast. It's not a normal memory leak, it's somehow very bad code that loops through something and allocates memory. Quickly. Within seconds half your swap is gone.

I have never seen this, but I primarily use telepathy-sofiasip on Maemo, with a different snapshot of sofia-sip.

Can you try to build sofia-sip from its darcs master repository at http://sofia-sip.org/repos/sofia-sip
 and see if this leak is reproduced?
