I'm not able to reproduce the crash.
(Ubuntu 8.10, 2.6.27-9-generic)

BTW:
There is no MozGest version compatible with Fx 3.2a1pre!
...at least I can't remember that I've released such a version.
yeah, well... please see the reports it's clear that this library (which i take it you're confirming is probably yours) is hurting someone.

actually, it looks like precisely one person:
Linux 0.0.0 Linux 2.6.27-9-generic #1 SMP Thu Nov 20 21:57:00 UTC 2008 i686 GNU/Linux

can crash reporter send people messages? i'd really love to send this guy one :(
If the user submitted an email, you could file a server ops bug to ask aravind to query the db directly for his email. Socorro doesn't have any functionality to do anything with email addresses as it stands.
One question:
What's the meaning of "Uptime 39"? Minutes, seconds, milliseconds?
And, yes "mgMouseService.so" is my library.

I still can't reproduce the crash though.
Uptime is seconds since the program started to the time it crashed.
i recently had a crash with this stacktrace, so I think this may be me. What do you need?
well, a couple of things would help.

1. you could load about:crashes and figure out which one is yours so that i know which one.
2. install -dbg / -debuginfo / symbols for at least libgdk-x11 libgdk-x11, ideally for everything loaded in gecko.

w/ a stack trace, it should be possible to try to figure out which functions were being called.

jochen: do you have debuginfo for your extension?
here's one I just got: http://crash-stats.mozilla.com/report/index/c747d524-7b1f-4132-9c04-697972081209

also: I'm not quite sure what you want me to install. care to explain what you want?
Ok, I can reproduce the crash.
http://crash-stats.mozilla.com/report/index/a8d93bd6-db8c-4ce6-9d59-123f52081210

There is no reliable way to reproduce the crash, but closing a tab will sooner
or later reproduce the crash after clicking on content.

In MozGest 2.0.3 mgMouseService.so is calling GDK_IS_WINDOW(xyz) and it's not
sure xyz still exists or is currently destroyed. 

https://addons.mozilla.org/en-US/firefox/addons/versions/39#version-2.1.0pre2
or
http://www.mousegestures.org/download/release/2.1.X/mozgest_2_1_0pre2.xpi
should work, because the crashing code was removed several weeks ago.
Both links should serve identical builds.

I wish there would be a simple (and frozen) way to get the window handle of 
the current content...

@Shayne Jewers:
Can you please download the above mentioned build and test it? Thanks!
Of course you have to bump compatibility to Fx 3.2a1pre... ;)

  "destroy-event"                                  : Run Last

try listening for these?

Well, to be honest, I wasn't aware of that.

The crashing code was removed weeks ago, because it wasn't needed.
It wasn't removed because it was crashing.

Is there a "lean and mean" way to get the window handle of the currently displayed content window? Maybe via "nsIWindowWatcher"?
fwiw, i had to ask a coworker, and i know for a fact that our (corporate) codebase crashes because of stale pointers such as these, so even though we know of it, it doesn't seem to mean we properly use it.
What a mess!

From my point of view the bug is already fixed because the upcoming version
of MozGest comes without the crashing code.

It's just a matter of time for review (AMO) though... 
The main problem for an update (AMO) is that mgMouseService is closed source...
I haven't had crashing in a while, so it looks like this is fixed.
Crash Signature: [@ mgMouseService.so@0x2ddd]
Portable Nightly 37.0a1 (2014-12-21) Have been using the Portable Nightly the past few days and trying to get mouse gestures to work, between All-In-One Gestures and FireGestures.  Have had some little successes.  I think the gestures interface is very important.  I have gotten used to using it.  No crashes at all since I've been using the Portable Nightly.
This is about a legacy add-on which is no longer compatible with Firefox 57, so closing.
