Description Christian Hesse 2014-06-02 13:51:41 UTC 
Installed latest version (claws-mail-3.10.0git2-pkg54), claws-mail crashes with libravatar plugin enabled:

* enable libravatar plugin
* select message in message list
-> claws-mail crashes

This worked perfectly fine with claws-mail 3.9.3-84 (or similar, do not remember the exact version).

I don't have Windows, so please post a backtrace to help debugging this.
Comment 2 Christian Hesse 2014-06-02 14:44:31 UTC 
I do have Windows, but no idea how to get a backtrace there. Anybody with a hint?

I got one:

Comment 4 Colin Leroy 2014-06-02 15:09:12 UTC 
Apparently auto configuration crashes if no DNS response to the SRV query exists.
Comment 5 Ricardo Mones 2014-06-02 15:30:36 UTC 
D'oh! That's a bit surprising, or not. Anyway as a workaround you can uncheck "Enable federated servers", which prevent this call from happening within libravatar.

In the long run this can be disabled when building for windows, for example, but better suggestions welcome.
Comment 6 Christian Hesse 2014-06-02 15:42:07 UTC 
The same happens when auto-configuring servers names.

So is the a bug in claws-mail or the glib version shipped with claws-mail?
Comment 7 Colin Leroy 2014-06-02 15:44:25 UTC 
I believe it's in glib, i'll investigate patching or upgrading our win32 glib: from a cursory glance, it's just trying to free an uninitialized result, and they've fixed it in at least 2.40.
Comment 8 Colin Leroy 2014-06-02 21:05:05 UTC 
Filed upstream with a patch, and a new build's uploaded.
