 OK, I am now positive this has nothing to do with epoll() vs. poll()
 (which was unlikely anyway but I wanted to test it just in case).
 
 I have just compiled 1.0.5 with poll() -- which means that its
 config and compilation options are pretty much the same as with the
 previous versions -- and the bug occurs again, just as it did with
 1.0.3/epoll().

 Looking at the backtrace and the code, it seems imap_fetch_deinit()
 is failing.
