           Summary: SEGV in newsnntp_date() -
                    mailstream_read_line_remove_eol()

I'm seeing a fairly regular SEGV in libetpan.so.18.2 on OpenBSD. Happens every
2-3 days for me.

Running under gdb shows the same backtrace each time, for example:

Thread 3 received signal SIGSEGV, Segmentation fault.

I haven't managed to make a debug build of claws-mail yet, so that's all the
information i have at the moment.
