lol Okay valgrind --log-file=/tmp/gnome-panel.valgrind gnome-panel is running. It's horribly slow but I'll try to keep working with it. How long should I run it ? btw, before I left for the holidays I installed an 11.1 on another machine and let it run in it's initial state. There seems to be no memory leak on that machine. Now if I compare that machine to my machine I have a strong feeling that it's the System Monitor which I have running on my machine that eats all the memory.

Well, if you can run it for a few days, that'd be great -- I know it's horribly slow, though, so I guess you'll stop it when you'll be really annoyed ;-)

Hrm. The thing is that the only in-process applet is the workspace switcher (and the logout buttons). The commandline and system monitor applets are out-of-process, and so the leak shouldn't appear in gnome-panel for them. But I fail to see how the workspace switcher would leak for one person and not for the thousands of other people out there... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Heh, you can read http://live.gnome.org/Valgrind to get some background about all this. The important thing is G_SLICE=always-malloc, since glib, by default, handles memory allocations in a smart way that doesn't work well with valgrind.
