Here's a backtrace from running pine in gdb and killing it when it's
frozen. It looks to me like KLAcquireNewInitialTickets, which isn't in the
API online at
http://web.mit.edu/macdev/Development/MITKerberos/MITKerberosLib/LoginLib/Documentation/API.html,
is what decides whether to get them from the terminal or from the
LoginHelper, and is deciding to use the Terminal. The last call in the
trace that's part of the Pine source is #14, gss_init_sec_context(). Is
there maybe a way to call that which forces the gui instead of the
terminal?
