Ok, I think I know what causes this problem but I don't quite understand 
what is the best way to fix it.

The extra sleep between gpgme_wait causes _gpgme_io_select to get signal 
on more than one file handler for the same context. As a result an error 
reported on the first handle causes all context handlers to be closed 
and the associated data released. When the second selected handle get 
processed it causes segmentation fault.
