[apport] gnome-panel crashed with SIGSEGV in _int_malloc() when upgrading a few packages

[Andrew Conkling]

Binary package hint: gnome-panel

I upgraded gnome-app-install and app-install-data and while Synaptic was installing them, gnome-panel crashed.

I don't mind at all, but for my own edification and bug triaging, why mark this one as a duplicate of a later one?

[Sebastien Bacher (seb128)]

I read the numbers too quickly, I've marked them the other way around now

Is there a way anyone can reproduce this? It happened twice before I reported it, but I can't seem to get it to happen again. I'm trying to get some useful valgrind output for the bug upstream.

[Sebastien Bacher (seb128)]

That's one problem with those bugs, they are not easy to triger to get the required informations to work on them

[Sebastien Bacher (seb128)]

That's probably a memory corruption problem, could anybody try to get a valgrind log (https://wiki.ubuntu.com/Valgrind) for it?

[Daniel Holbach (dholbach)]

Upstream closed the bug. Please reopen, if it still occurs and you can provide more info.

[Andrew Conkling (andrewski)]

Here's a valgrind log from my system. No crash :(, but perhaps something useful here; I ran it for days. (I'm mostly posting this to link to it upstream; it's too big for bugs.gnome.org.)

[Sebastien Bacher (seb128)]

Did you open a bug upstream about that? That's likely to be a duplicate from bug #85776

[Andrew Conkling (andrewski)]

There's a bug upstream attached to this bug; that's the one I mean.

[Adam Petaccia (mighmos)]

I believe I just ran into this bug.

[Andrew Conkling (andrewski)]

Every time I try to reproduce this bug in Valgrind, it fails to crash. Considering how often this happens on its own, It seems plausible that someone could try a Feisty beta CD and upgrade the packages there?
