gpg related crash/hang on 2.0.11

[Nuno Monteiro <nuno itsari org>]

Hi all,


I'm experiencing a weird hang/crash with Balsa 2.0.11 when opening a 
_specific_ gpg signed email. I tried to reproduce it with every other 
signed email I had around, but it seems it'll only choke on this one. 
Whenever I double click on that particular email from the list, Balsa 
hangs and stays like that forever (well, until Gnome asks me if I want 
to kill the window, at least). The system is a fairly stock Mdk 9.1 
installed a week ago, gpgme is version 0.3.15, and works otherwise 
great. I got this backtrace from gdb:

libpthread is linked before libgpgme as it is supposed to be:

nuno@hobbes:~/src/balsa/src$ ldd balsa|grep -n '\(pthread\|gpgme\)'
14:     libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40269000)
43:     libgpgme.so.6 => /usr/lib/libgpgme.so.6 (0x40df6000)


I'm also attaching a gzipped version of the offending email, in case it 
is needed to debug the problem further. Let me know if you need 
anything else.


Cheers,


			Nuno
