[Bug 289264] [NEW] Memory leak in update-notifier-kde

[Julien Aubin]

Public bug reported:

Binary package hint: update-notifier-kde

I've seen a memory leak in update-notifier-kde package. Each time you
update the package list with the aptitude update method, the memory used
by the process increases but never decreases then.

How-to-reproduce :
----------------------------------------
DO: launch the update-notifier-kde process
DO: run top or htop and sort processes upon the used memory.
DO: launch several times an aptitude update command.
You can run the following command as root in order to save time :
for i in `seq 1 50`; do sudo aptitude update; done
EXPECT: the memory used by the update-notifier-kde process increases a lot, more than 100 MB used at the end of the for loop !!!

The issue should have a very low impact in most of the cases, but for a
production machine that runs 24/7 this can become resource-critical.

Release used :
Kubuntu 8.10
Package revision : 0.9

I suspect the issue from coming from one of the following lines (my
knowledge of Python is NONE ;-) ) :

Line 103:        self.new_dist = metaRelease.new_dist // Any garbage connection of the old new_dist reference if any ?
Line 124:        self.new_dist = metaRelease.new_dist // Same comment
