[Gnubiff-devel] SEGV: in SSL_write() via idle_renew_loop()

[Calum M. <cal...@cd...>]

Just received a SEGV, a few seconds after starting gnubiff; give the 
stack I wonder if this is related to Byron's new idle renew stuff?

It fails repeatedly, every time I restart gnubiff, and always after the 
same debug msgs:

** Message: Applet update
** Message: [11] RECV(diesel.cimr.cam.ac.uk:993):

** (gnubiff:5547): WARNING **: [11] Unable to read from 
diesel.cimr.cam.ac.uk on port 993
** Message: [11] CLOSE diesel.cimr.cam.ac.uk:993
** Message: [10] RECV(localhost:2143):

The above msgs are the same for each failure.

cheers,
c.
