Comment 1 Sven Brauch 2013-05-02 16:24:14 UTC 
Can the bug be reproduced?

Could you maybe run the application through valgrind to get more detailled information? It's very unclear how this can happen, and nobody was able to reproduce it so far. The valgrind logs are clean, too.

[17:34] <d_ed> so, to reproduce:
[17:34] <d_ed> close the wallet
[17:34] <d_ed> (make sure it has a password)
[17:34] <d_ed> open system settings
[17:34] <d_ed> click edit
[17:35] <d_ed> ignore the wallet prompt
[17:35] <d_ed> and click close
[17:35] <d_ed> our app gets killed (from the inner event loop) 
exec finishes and we're in a broken stack.. double free.  BOOM
